50
|
* - RPMessage_ResourceTable copied from Linux IPC example ti_drivers_config.c
|

51

52
|
* - gDebugMemLog copied from Linux IPC example ti_dlp_config.c

53
|
*
|
|
54
|
* - Should I just delete gDebugMemLogSize? Or is it used somewhere?
|
|
55
|
*
|
|
56
|
* - I do NOT expect the log to be viewable from Linux, because I did not
|
|
57
|
* copy this part of ti_dlp_config.c:
|
|
58
|
* void putchar_(char character)
|
|
59
|
* {
|
|
60
|
* // Output to memory trace buffer

61
|
* DebugP_memLogWriterPutChar(character);
|
|
62
|
* }
|
|
63
|
*
|
|
64
|
* - Future work: try reducing the size of the DebugP log buffer if not used
|
|
65
|
* It takes 0x1000 of space in .bss by default
