Part Number: MSP430F5510
Please refer to the schematics below. (Just a relevant part)
I'm at the stage of prototype bring-up.
My USB host doesn't see the MSP as one of the devices.
There's no oscillation on Y1 crystal.
The 3V3_MCU voltage is 2.77V (According to the spec it is supposed to be 3.3V ± 9%)
There's a solid 5V supply at the VBUS port.
Haven't used the JTAG programming yet - trying to work with the factory preprogrammed condition.
Am I missing something wrong in the schematics?

Hi all, I am using MSP-EXP432P401R (Red) and testing two UARTs, uart0 and uart1. They are configured as CONFIG_UART_0 and CONFIG_UART_1 as follows. CONFIG_UART_1 is connected to another notebook via RS232 interface. I tested my customized RS232 connector with null modem successfully.
I connected my own customized RS232 connector to P3.3(4), P3.2(3) and GND(22). I use only 3 pins: RX, TX and GND.
If I use only uart0, there is no problem as in following screen capture:
If I use uart0 and uart1 together, all data from/to uart1 are broken as following screen shot:
<< screen shot of PC connected to uart0>>
<< screen shot of PC connected to uart1>>
Attached source, console.c
void *consoleThread(void *arg0)
{
char ch, cmnd_in[80], bbff[80], itoa_buf[5];
int i, len, cnt ;
cnt = 1;
/* Loop forever to start the console */
while (1) { // today
memset(cmnd_in, 0x00, sizeof cmnd_in);
cmnd_in[0] = 0x0d;
cmnd_in[1] = 0x0a;
UART_write(uart0, consoleDisplay, sizeof(consoleDisplay));
UART_write(uart0, userPrompt, sizeof(userPrompt));
i = UART_read(uart0, cmnd_in + 2, 20);
if (i != 20) {
while(1) ;
}
itoa(cnt, itoa_buf);
strcat(cmnd_in, " - ");
strcat(cmnd_in, itoa_buf);
UART_write(uart0, cmnd_in, strlen(cmnd_in));
UART_write(uart0, "\r\n",2);
i = UART_write(uart1, "\n\rEnter 20 chars : ", 19);
if (i != 19) {
while(1) ;
}
i = UART_read(uart1, bbff, 20);
if (i != 20) {
while(1) ;
}
UART_write(uart0, "\r\n\n", 3);
UART_write(uart0, &bbff[0], i);
UART_write(uart0, "\r\n\n", 3);
++cnt;
}
}
Please kindly advise me what I make mistake.
Any help and advise are appreciated.
Many Thanks in advance.

Hi Experts,
Recently I was migrating one code from Code Composer Studio to IAR after doing all these thing in IAR it asked for .cmd file for building the project but ,cmd I added that only which was given in Code Composer Demo Codes. So can I use .cmd file for CCS to run in IAR or what to do please give me answer I'm Confused.

I've been working through the example uses of the bootloader, currently sourced from SDK v.3.20.00.10. Primarily I am interested in developing applications that will make use of the ethernet bootloader over tftp.
I've been able to successfully deploy the boot_serial_emac_flash examples, all of which use lwip and are without any RTOS implementation.
I would now like to develop an example that uses FreeRTOS and also incorporates the NDK as opposed to lwip for TCP/IP set up, but I'm having difficulty getting it to function. What are the problem areas here that I need to be aware of to add this functionality, or is it not possible?
For example, what primary steps would I need to take to adapt the FreeRTOS flavor of the 'tcpecho' example for deployment over the ethernet bootloader?
Thanks

This question is targeted at the PC/build side of the project described in the related question. I need to calculate CRCs for the text and rodata sections of my application during the build process. Those values will eventually be compared against CRC values computed during run time by the MSP430.
In the related question, I found out that the CCS linker performs section CRCs during the build process. However, I have been unable to find equivalent functionality in the MSP430-GCC documents I've reviewed. Does the MSP430-GCC linker include this functionality or is it only available in the TI CCS linker?

I have an application that makes use of a lot of peripherals, including a timer that calls a handler at periodic intervals. If there is no watchdog reset, everything runs as expected.
If I comment out the code to feed the watchdog, the rest occurs after the expected delay, but the MSP430 does not appear to really be doing a "full" reset of the timer peripheral. After the watchdog reset, TA0_TA0CCTL0 contains a value of 0x01. This indicates that the timer interrupt (TAIE) flag has properly been cleared, like it should, but the interrupt flag (TAIFG) is set, indicating a pending interrupt!
What can I do to clear all interrupts that could have been pending/active before the watchdog reset, so that my interrupt handlers cannot execute before application initialization?
Pseudocode:
void main()
{
// (Never reaches here after a watchdog reset)
// Initialize application data (pointer initialization, heap allocation, etc...)
// Initialize watchdog
ROM_WDT_A_initWatchdogTimer(WDT_A_BASE, WDT_A_CLOCKSOURCE_SMCLK, WDT_A_CLOCKDIVIDER_8192K);
ROM_WDT_A_start(WDT_A_BASE);
// Initialize other peripherals, including a hardware timer
for (;;)
{
// Feed watchdog
ROM_WDT_A_resetTimer(WDT_A_BASE);
}
}
void timerInterruptHandler()
{
// Accesses application data, which must be initialized before this is called, or the application crashes
}

Hi,
It was recently brought to my attention that there is a better ADC and EVM (ADS124S08) I can use for my RTD setup. Is the ADS compatible with the MCU that was recommended for the 1247 ADS and EVM setup? I am using an Pt100 RTD grade 1/10 din in a 4 wire configuration and need to have a MCU setup to transmit the data onsite.
Thanks, Sid

On a brand new installation of CCS 9.2.0 with the latest codegen tools, when I import a CCS example from MSP432E4 SDK 3.30.00.22, I get the error:
"No TI MSP432 compilers, supporting device 'MSP432E401Y', are currently installed!"
This occurs on any CCS import. With a GCC import, it imports and compiles properly. Doe the codegen 18.12 no longer includes TI compilers for MSP432E?
Also, what SYSCONFIG example are available for No RTOS? Seems they are only in the /ti/simplelink_msp432e4_sdk_3_30_00_22/examples/nortos/drivers directory.
Best regards,
Pedro

is it possible to code in python and then reload in this via some other source. Is it necessary to code in C/C++ in the MSP430F5529, I would be obliged if you revert me bak with positive response to this question.
Part Number: MSP432P401V
Hello,
While trying to compile the driverLib `spi.c` against the MSP432P401V part using IAR I receive the following errors:
Error[Pe020]: identifier "EUSCI_B1_BASE" is undefined ....\spi.c 467
Error[Pe020]: identifier "EUSCI_B1_BASE" is undefined ....\spi.c 516
This is because these registers are not defined in `msp432p401v.h`.
Can anyone else verify this error?
Thanks,
Dominic

Hi There.
We have to share some source code with a third party but we are trying to hide our intellectual property.
We are thinking to separate critical functions into libraries and then compile them into binaries; then link them later on.
Does anyone have another approach or recommendations on how to do this?
Thanks

G'Day all,
In the last few days I updated CCS from v9.1 to v9.2 and I've noticed that the RTOS Analyzer and System Analyzer options from the tools menu (in debug view) are gone.
Same is true for all my colleagues who have done the update.
Can you help me find the RTOS Analyzer tools (Execution graph in particular) in CCS9.2?
Cheers

Hi,
My name's Manish.
This MSP430FR5043 is a custom board and I'm actually trying to talk to RTC module through SPI peripheral.
The data which I'm sending through the Tx buffer to the RTC module through SPI is verified, but I'm not receiving anything back from RTC module. I've set the UCLISTEN bit to enable loop back mode which will enable for echo mode.
I need help in the following steps, any example for anything that might help,
Thanks in advance,
Yours Sincerely

Hi Dennis,
Since I have been unable to use the MSP430F2013 on both of my MSP-EXPFG4618 experimenter boards, I decided to attempt connect to the MSP430FG4618 JTAG interface and loading some sample code onto them, however, as soon as I load the binary, and attempt to run the code, the LCD display stops working and it appears as if I am hitting a breakpoint.
As mentioned, my laptop is running Ubuntu 19.10 and I am using the msp-elf-gcc version 8.3.0.16 compiler and building the TI sample code for this board.
As with the previous experience, attempting to load code onto the MSP430F2013, it is visibly obvious that the MCU is no longer functioning, since, after power-cycling the board, the factory-default code, which normally causes the LED3 to flash, stops working.
In the case of the MSP430FG4618, the LCD no longer displays anything.
In none of these tests which I have carried out, have I attempted to program the flash memory on either MCU.
I now have two boards which are dead and am unable to proceed any further.
I would be most appreciative of your assistance in resolving these issues please.
I have attached the source, object and binary files which I attempted to load onto the MSP430FG4618, in a slac129_lcd.tar.gz archive, for your reference.
Thanks in advance.

I was going through the MSP432 BSL User guide and I had one doubt which I want to ask
I understand that in order to perform hardware invocation of the BSL, we need to program the flash mail box with MB_START, CMD and other appropriate parameters and do a reboot.
Bootcode will now take the control and it will see boot override request and it will perform the request by parsing the flash mailbox and associated CMD.
If the boot override command is BSL_CONFIG, I can see that the bootcode executes the command and write 0x00000ACE to the ACK (0x1F4 offset from flash mailbox start address) and writes NONE (0x00000000) to the CMD field (0X04 offset from the flash mailbox start address).
My doubt is "TI mentions that once you have provided the pins and their state for the hardware sequence entry, the device will go into BSL mode if the same sequence is present during boot time".
But I think that bootcode first checks the command field and if the command is BSL_CONFIG, it extracts the BSL hardware invoke parameters (0x1E8 offset from flash mailbox). Since, BSL writes none to this field on successful execution of command, on next reboot how does the bootcode knows that it has to enter into the BSL (based on the hardware sequence entry) since the command is NONE by now.
Please help me understanding this part of BSL.
