R5 programming JTAG port open error. AP transaction error, DAP status 0x30000021

[jsm]

Hi all,

I am unable to program the TE0802 R5 processor, as it shows this error:

xsct% Info: Cortex-R5 #0 (target Stopped at 0x0 (Cannot resume. AP transaction error, DAP status 0x30000021)

I am generating a project with the default Trenz configuration, it used to work fine. Then I tried to configure the FPGA using some bitstream file using xsct (fpga <bitstream>)

Now I am back to my previous project with the SDK, without any changes in SW or FPGA. I see the PL gets written but now I cannot access the R5.

Any ideas?

xsct% targets
  1  PS TAP
     2  PMU
     3  PL
       13  Legacy Debug Hub
  4  PSU (JTAG port open error. AP transaction error, DAP status 0x30000021)
     7  RPU
        8* Cortex-R5 #0 (Cannot resume. AP transaction error, DAP status 0x30000021)
        9  Cortex-R5 #1 (Reset)
    10  APU
       11  Cortex-A53 #0 (Breakpoint, EL3(S)/A64)
       12  Cortex-A53 #1 (Power On Reset)



Thanks,
Juan.

Solved by rebooting the PC

Hi,
if reboot has help, maybe kill one time the hw_server.exe manually on win task manager if you, this helps also in many case when you has problem with JTAG.
