MSPM0L1304: I2C pins remapping for BSL

Part Number: MSPM0L1304

Hi Team,

Posting on behalf of our customer.

I'll share this E2E post with our customer so he can reply when needed.

I am working on mspm0l1304. I want to flash the code over i2c. the issue is MCU is soldered on custom PCB and ROM BSL defauult i2c pins are not accessable at all. I want to use i2c1 pins for this purpose.

there are 2 exacmples projects:
1. bsl_i2c_flash_interface  (I tried this one but I realise I can't remap the i2c pins using interface override / plugins)
2. secondary_bsl_i2c ( I am working on it I am adding i2c1 as peripherals but then it is generating ti_msp_dl_config.h file cause conflicts with the provided ti_msp_dl_config_h file).


Am I now looking in the right direction?
if yes, how to resolve this issue?

Regards,

Danilo

    Hello Danilo,

    Because you just want to change to use I2C0, you don't need to do the secondary BSL. 

    You can do some modification based on bsl_i2c_flash_interface. You need to change some definition in the ti_msp_dl_config.h file 

    In this file, you can see there are many definition of I2C usage. Change them as what you want. 

    The BSL_GPIO_I2C_SDA_PIN and BSL_GPIO_I2C_SCL_PIN is the pincmindex of the I2C pin you choose, please check it from datasheet. BSL_GPIO_I2C_SDA  and BSL_GPIO_I2C_SCL is the function number you choose of the pin. For your better understand, you can read below function where use the BSL_GPIO_I2C_SDA_PIN, BSL_GPIO_I2C_SCL_PIN, BSL_GPIO_I2C_SDA, BSL_GPIO_I2C_SCL
