The ap debug base address is 0x80000000, you can se this in the romtable information for DAP #1 with dap inf 1. Here you can also se the offsets from the debug base address to the debug component adresses. To get the memory address in the MEMAP memory map you must add base+offset: ( the 2 LSB bits are status and not part of the address) 0x80000000+0xD4010000 = 0x54010000 ( unsigned 32 integer addresses ) So the values given in OMAP35x TRM table 1.52: Debugger Address Space are not the memory bus addresses but the offsets from the romtable base address. More information can be found in the ARM Debug Interface v5 Architecture Specification, ARM IHI 0031A, sec. 8.1.3 and 14.6 Best regards Magnus _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
