We are using Cortex-M0 DesignStart Pro to design MCU. When we use SWD to download grogram to flash in FPGA(Cortex_m0 mcu inside), we cannot to connect keil with FPGA, and Keil shows:" Could not stop Cortex-M device!Please check the JTAG cable. "
Attached are keil display error messages, simulation waveforms, and data analysis captured by the logic analyzer.
Thank you very much! If we use one of these probe, can we directly access FLASH, to debug the SOC system?For our SOC FLASH access system, do we need to do anything with probe? Do we need to design for SWD in SOC?
