MSP430FR2433: Unable to program microcontroller over I2C bus on bullseye image of RaspberryPi.

Parth Goel

We updated our RPi image from Buster 32-bit to Bullseye 64-bit and cannot program MSP430 over the I2C bus (i2c-0). We are using msp430-i2cbsl-tool to flash it, and I had to make it again for the new OS. I am also getting extra I2C devices in /dev directory in Bullseye image - i2c-10, 11 and 2. I have also added this in my config.txt ->

#-- enabled I2c1 & I2c-0 ---
dtparam=i2c_arm=on
dtparam=i2c0=on

Attached are some screenshots of the flashing process and errors -

1. With RST and TEST Sequence ->

2. Without RST and TEST Sequence ->

Hi Parth,

Do you try to capture RST and TEST pin wvaeform? If BSL invoke fail, maybe you can find something in those waveform.

And run BSL scripter in Linux system? Have you try our Linux Tools?

Thanks!

Hi Johnson,

We are already using the tool you have mentioned and it is probably not an issue of RST and TEST waveform. We are using the same procedure that works in RPi Buster 32-bit OS but not working in RPi Bullseye 64-bit OS. We are also unable to detect MSP430 on I2C bus using i2cdetect command.

Parth

Hi Parth,

Looks run in RPi 64-bit OS encounter this issue, actually, I am not a expert for linux..... I am not sure if there are some different between 32-bit OS and 64-bit OS for RPi Bullseye.

Thanks!
