how to enable am335x Monitor debug-mode

Pingchuan Ma

Hi ,

The monitor debug mode can be configured in DSCR, which is writable via APB interface for am335x. But, I read the DRAR(MRC p14, 0, <Rd>, c1, c0, 0) and DSAR(MRC p14, 0, <Rd>, c2, c0, 0). Both of them are invalid value (both are 0).

My question is how to enable am335x Monitor debug-mode? Thanks a lot.

Thanks,

Pingchuan

This is a generic ARM question. Please refer to http://www.arm.com/ and forums on that site. The AM335X has a JTAG interface for debug purposes.

Hi Biser,

This may NOT be a generic ARM issue. Because I tested on Freescale IMX53 board, which is also a cortex-a8 core board. The registers DRAR and DSAR is right. Any idea? Thanks a lot.

-> drarGet
value = 1610612739 = 0x60000003
-> dsarGet
value = 32771 = 0x8003
