Hi, I use JTAG HS2 with Synopsys Metaware for ARC debugging. I can download the information successfully. However, the speed is very slow. The download speed is about 1KB/s. I checked the protocol with logic analyzer and found the root cause is that the gap between IR and DR is about 1ms. One DWORD takes IR-DR-IR-DR. Was the gap caused by HS2 HW, driver or software? Thanks!
Hi! I am currently working on a project which uses a particular version of an ARM Cortex M0. Therefore I can not use Xilinx' tools to debug the ARM core directely. Using a Nexys 3 with a Spartan 6 I am looking for other ways to debug it: In the ARM forum a user pointed out that ARM has a debugger platform called CMSIS-DAP. Does Digilent support this platform? I currently use a JTAG USB debugger from Digilent, does it support CMSIS-DAP?If not, do you know of any other possibility on how I could debug the ARM core directly and without using Xilinx tools?Any help is much appreciated!
