Hello,
I am trying to debug the Linux Kernel remotely using KGDB over the serial port.
I followed the instruction shown here: https://elinux.org/images/1/1b/ELC19_Serial_kdb_kgdb.pdf but can't make it to work. This is what I get:
I have the idea that it may involve the polling functions lpuart32_poll_put_char and lpuart32_poll_get_char but I do not know how to debug it.
It would be great to know if someone from NXP ever tried it.
BR,
Lorenzo
Hi Lorenzo
one can look at Uboot/Kernel/SCFW debugging documentation AN12631
Normal and Secure Debug for i.MX8/8X Family of Applications Processors
Lauterbach debug tool : TRACE32 as GDB

Best regards
