MSPM0L1105: Bootloader mode, i2C address 0x48, no response when sending Connection request

Hello Roger,

Firstly, you need to do BSL invoke, using hardware BSL invoke pin or using SW way. Then we have the default I2C BSL pin, please check whether you use the correct one if you don't re-configure the BSL I2C pin.

We connected an I2C analyzer, see a write request going to address 0x48. No ACK, no response.

We enter the BSL using the SW way.

Our application blinks an LED, the LED stops blinking leading us to believe we are no longer in the application, entered BSL?

Is there a way we may confirm this?

Our BSL I2C Pin Configuration as follows:

I2C Peripheral - I2C0

I2C SCL Pin - PA1/NRST

I2C SCL Pad Number 2

I2C SCL Mux - 3

I2C SDA Pin - PA0

I2C SDA Pad Number - 1

I2C SDA Mux - 3

I2C Target Address(7-bit) - 0x48

Can you provide further assistance? We've tried the hardware invoke and the software way, neither gets an ACK from I2C.

Our application code uses address 0x11 which works, able to read/write.

Haven't been able to make contact when entering Bootloader.

Hello Roger,

Get it. I will take a look into the information and do tests if needed, and then come back to reply to you.

Problem solved.
