AM263P4-Q1: Minimum Configurations Required to Allow Debug Logs from UART

Hi Mari,

You can enable DebugP_logs from syscfg with steps shown below (by default, enabling UART logs from Syscfg -> Software -> Debug Log, will add a UART0 instance):

Restrictions:
1. Do not use DebugP_log in code related to performance or benchmarking, UART streaming is generally slower and will take up resources.

2. Do not use DebugP_log or any logging in any ISR content. All the ISRs should be executed within a fixed, deterministic and small time

3. DebugP_logs can be used outside ISR context in code which is not time-critical.

Alternatives to DebugP_logs are to either log data somewhere in a fixed memory in OCRAM and then periodically read and dump that over UART (this won't be real-time logging though)

Or if other R5F cores are free, you can execute your main code on Core0, log data in Shared memory and use Core1 for logging purposes (e.g. DebugP_log over UART)

You can also have a look at real-time debug if needed: https://software-dl.ti.com/mcu-plus-sdk/esd/AM263PX/latest/exports/docs/api_guide_am263px/REAL_TIME_DEBUG_SUPPORT_GUIDE.html
