PROCESSOR-SDK-J722S: J722S mcu10, how to print log outside task?

append:  i've seen the

1.  https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-j722s/11_00_00_06/exports/docs/mcu_plus_sdk_j722s_11_00_00_12/docs/api_guide_j722s/KERNEL_DPL_DEBUG_PAGE.html  , it says not work in irq,

2. souce code,  it calls SemaphoreP_pend  to make thread safe.    so it may not work outside a task function.

so, is there a way to prinit debug info under these 2 situation?

Hi,

ui he said:

1. when in irq callback like App_mcanIntrISR, it not print anything, but program still running.

Printing in ISR like App_mcanIntrISR should be the same way as you printed the debug logs. If it does not print anything, maybe the MCAN ISR is not reached.

2. when print outside task, eg. before call  xTaskCreateStatic,  the app not running.

What debug information are you trying to print before the task starts?

Yes, that is correct so it depends at what point you are trying to print. Do you attempt after Dpl_init() or before?

Thanks,

i want debug some before a task create, eg, during  `System_init()`  or Board_init() function  after main started,   i just want to use it during development, and dont want any task safe protection,  is there any uart api tx function send data to pc directly ?
