Linux/MSP430FR2633: Booting MSP430FR2633 over I2C

Part Number:MSP430FR2633

Tool/software: Linux

Hello,

We have connected I2C, TST, RST and the VCC, GND between our test board and the MCU430FR2633 board of the MCU development kit. We are quite sure that everything is connected correctly.

We try to boot MSP430FR2633 over I2C, according to this document:

http://www.ti.com/lit/ug/slau610c/slau610c.pdf#page=6&zoom=auto,0,555.1

So, first step toggling TST and RST according to 3.5.2 in order to enter the BSL mode.

Now we were sending a command via I2C, but we never received an ACK on the address 0x48. We measured the signals and everything looked OK, beside that we do not get any answer.

Thanks in advance for help

Santhosh and Astrid
