I've tried the following lines for the openocd configuration file, if you need any help let me know! # --- emev2 (CA9 Dual) on KZM9D --- #target create emev2.cpu0 cortex_a -chain-position auto0.tap -dbgbase 0x80010000 -coreid 0 #target create emev2.cpu1 cortex_a -chain-position auto0.tap -dbgbase 0x80012000 -coreid 1 Cheers, / magnus -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
