MSP432E401Y: Bootloader on UART other than UART0

Victor Tolosana

Part Number: MSP432E401Y

Hello,

Is it possible to update the MSP432E401Y's firmware via UART4 (instead of the default UART0) ?

If yes, how to do so ?

Thank you.

Regards,

You can't use the default bootloader via UART4. Maybe you need a customized one.

Ok, by that you mean modifying bl_uart.h in boot_serial_uart_flash_MSP_EXP432E401Y_nortos_ccs ?

Changing all #define with adequate pins for UART4 should make it work ?

Thank you very much.

You can see that the default bootloader is in ROM:

The one you find is an Application bootloader saved in flash. You can customized it as what you want.
