I want to enable live debugging via the DEBUG register of the ARC600 as shown here: http://me.bios.io/images/d/dd/ARCompactISA_ProgrammersReference.pdf I have been checking the file wil6210.h and I understand that some of the registers are defined there: /* registers - FW addresses */ #define RGF_USER_USAGE_1 (0x880004) My question is regarding this mapping, I see that the names are not the ones of the Core Register Set or the Auxiliary Register Set (r0, r1, STATUS32, DEBUG and so on). My question is how could I find the addresses to those registers? Let's say I want to write read to the DEBUG register (0x0) on the MAC and on the USER cores, how could I do that? What is the offset to those registers? If successful I will try to document all hardware addresses and hopefully implement further debug capabilities and send a patch! ------ Pablo Jiménez Mateo, PhD student, IMDEA Networks
