MCU-PLUS-SDK-AM273X: Unreliable debugging of multicore applications

Tool/software:

Hello! I have two questions:

1. Is there a way to make the flashing with `uart_uniflash.py` faster? E.g. by increasing the baud rate? The script has the function `xmodem_send_receive_file()` that takes `baudrate` as the third argument, but none of the calls of the function uses non-default baud rate. I guess we would have to re-program XDS110 to use another baud rate?

2. When running an application from FLASH, could we get the logs that are logged to CCS somehow on the host PC? When logging to CCS, the syscfg generates such a function inside `ti_dpl_config.c`:

Is it possible to get the logs without CCS being involved?

    Hi Kacper,

    1. Yes, you can change the baud rate from the default 115200 (in C:\ti\mcu_plus_sdk_am273x_09_02_00_52\tools\boot\uart_uniflash.py), but you also need to change the baud rate in sbl_uart_uniflash. By default, it is 115200 too. After the change, you have to re-build the sbl_uart_uniflash and replace the C:\ti\mcu_plus_sdk_am273x_09_02_00_52\tools\boot\sbl_prebuilt\am273x-evm\sbl_uart_uniflash.release.tiimage

    2. All you need to do is uncheck the "Enable  CCS Log" in the example.syscfg and rebuild the CCS project.

    Best regards,

    Ming
