Linux/MSP430FR2633: Firmware Updates Over I2C Using Linux

Peter Tsao

Part Number: MSP430FR2633

Tool/software: Linux

Hi all,

I have several questions about FR2633, please help me find the answers.

By using Raspberry Pi as the host, what else in the msp430_i2c_bsl_linux_tools should be modified?

I have tried this many times, but still fail in the WriteRead and Write function in the i2cbsl.c

For this tool, could I use the hes file that just built by CCS? Or I need to flash the txt one?

Should I build or flash the BSL? Or it just default in the chip?

Is there any document to teach how to tune the MSP430 by Design Center?

Thanks,

Peter

The problem is in MSP430BSL_I2CWriteRead function.

If I want to send the password, the xferBuffer packet will be

[0] Header

[1] Length

[2] Lenght >> 8 & 0xFF

[3] Command

[4] ~ [35] password (all 0xFF)

[36] crc16 & 0xFF

[37] crc16 >> 8 & 0xFF

But when I use logic analyzer to see the I2C packets

the packets [26]~[33] will not transfer

I am not trying to find the solution
