MSPM0L1105: I2C error when doing Host_BSL_MassErase

Jonas Liang

Part Number: MSPM0L1105
Other Parts Discussed in Thread: MSPM0L1306

Dear Ti team,

We want to flash firmware to our MSPM0L1105 target by i2c.
And we reference the code form C:\ti\mspm0_sdk_1_30_00_03\examples\nortos\LP_MSPM0L1306\bsl\bsl_host_mcu_to_mspm0l11xx_l13xx_target_i2c.
Now we encounter a situation in Host_BSL_MassErase function.
// Write the packet to the target
i2c_ack = I2C_writeBuffer(BSL_TX_buffer, HDR_LEN_CMD_BYTES + CRC_BYTES);
if (i2c_ack != uart_noError) {
TurnOnErrorLED();
}

I2C_readBuffer(BSL_RX_buffer, 1);
delay_cycles(2000000);
I2C_readBuffer(BSL_RX_buffer, HDR_LEN_CMD_BYTES + MSG + CRC_BYTES);

I2C_wirteBuffer part looks good, it can write 8 bytes successfully.
But system i2c shows "controller timed out" when doing next "I2C_readBuffer(BSL_RX_buffer, 1);"

And then we can't do further actions.

Could you tell me how to do Host_BSL_MassErase by i2c flashing firmware correctly?

Thanks!

Hi Jonas,

Did they met questions with example code? Or the example code was ok but their code went wrong?

Thanks,

Yuhao

Hi Yuhao,

I just reference the example code. I have no idea if example OK or not.

i2c read buffer has problem after I2C_writeBuffer.

Sometimes "I2C_readBuffer(BSL_RX_buffer, 1);" works but the next read stil failed.

It's a urgent issue. Please help to check ASAP.

Thanks!

Actually you can run the example code first by following the readme in the project.

But could you contact with any TI FAE?

It would be better to discuss via email if the case is urgent.

Attach the complete log for your reference, you can see read failed happend after mass Mass Erase command.

Hi Jonas,

Since support is via email, I will close the thread now.

Thanks,
