TEBT0808 and TE0808
« on: June 16, 2022, 08:09:29 PM »
I am attempting to flash a TE0803-04 (TE0808-04-9GI21-A) via the PS JTAG USB link TE0790. These were ordered separately from each other and therefore I believe that the SOM does not have any firmware loaded in the QSPI Flash.

1. Could you please provide a TCL script of successful building / programming of a device ? I have found resources at the (Project Delivery) and have been having a few issues with the target not connecting or providing access to the full target list:
xsct % connect
xcst% connect
xsct% targets                                                                                                                         
  1  PS TAP (Cannot poll JTAG port: CBR not done, debug access not allowed)
     2  PMU
     3  PL
  4  dummy_dap

# Then some time later, with apparently no deliberate input
xsct% targets                                                                                                                               
  1  PS TAP
     2  PMU
     3  PL
  5  PSU
     6  RPU (Reset)
        7  Cortex-R5 #0 (RPU Reset)
        8  Cortex-R5 #1 (RPU Reset)
     9  APU (L2 Cache Reset)
       10  Cortex-A53 #0 (APU Reset)
       11  Cortex-A53 #1 (APU Reset)
       12  Cortex-A53 #2 (APU Reset)
       13  Cortex-A53 #3 (APU Reset)
2. Is there a way to tell if a part is damaged? The device can be successfully programmed, but I have yet to see a full sign of life as the UART connections maybe need to be remapped in the vivado project to map to the input of the TE0790.

3. Why is the file in the prebuilt versions called hello_te0807? This appears to be the wrong board, and I have checked the downloads and part selection (33) several times.

EDIT: Resolution to 1 and 2 are that the board was defective, long boot loading times and error indicators led to debugging physical power supply issues that are probably specific to my situation.

in case you see "dummy_dap" than PS is not ready. Check DIP Switches for power and also boot mode(should be jtag only).

Check also your external power supply.
