I am using ULINK to debug the LPC2132 board. They work well for some days. But now a problem appeared. Everytime I want to download code to FLASH, always get"Could not stop ARM device, please check your JTAG cable?" But JTAG can be detect on Option for device. I do not know what is wrong? Thanks in advance for any idea.
have no experience with "your board" but have blown a JTAG or two by 1) hotplugging (takes many 'tries' to blow it that way) 2) missing ground between the two 'ends' Erik
And I probe every JTAG pin signal.Only RCLK has nothing happen. RCLK is necessary? thanks
