Currently OpenOCD always flushes and invalidates caches, even if they are not present. That is mostly ok, because if caches are not present then invalidate/flush commands are ignored. However JTAG...

Code to single step in OpenOCD is wrong: >>>> //retval = arc_jtag_read_aux_reg(&arc32->jtag_info, AUX_DEBUG_REG, &value); value = SET_CORE_SINGLE_INSTR_STEP; /* set the IS bit */ retval = arc_jtag_write_aux_reg_one(&arc32->jtag_info, AUX_DEBUG_REG, value);

In GDB for userspace there are problem with handling breakpoint set in delay slot. Unlike baremetal tool chain where BRK instruction is used, GDB for Linux uses TRAP_S which is...

Allow OpenOCD to write into SPI memory in EM Starter Kit device. OpenOCD already supports many NOR/NAND devices. Implementing this feature will allow users to change program images in EM...

Review status of gold linker and evaluate whether we should convert from standard linker to gold linker for ARC.
