Jul 19 14:45:36 <None__> Hi all. I am developing a custom JTAG program for a custom JTAG device I did. So I started to read the ARM Debug Specification V5 (didn't find V7 or V6). I focus on th AHB-AP to perform read/write through JTAG DP. I don't want to implement all JTAG features, r/w is enough. For the moment I am trying to read the IDCODE. But I am stuck
Jul 19 14:47:12 <None__> When I move the IR Shift to send IR 0111 I get the correct output on tdo : 1000. Next I move to Shift DR to read the 32 bits but TDO stay at 0... Any idea please ?
Jul 19 14:58:59 <None__> I solved the problem
Jul 19 14:59:06 <None__> God bye !
