ZCU102 fails from SD card BOOT, UART has no output

ZCU102 fails from SD card BOOT, UART has no output
It can be confirmed that the configuration board has no problem booting from the sd card because it was successfully started before (using https://www.xilinx.com/products/design-tools/ai-inference/ai-developer-hub.html#edge) Mirror file), and there is a graphical interface, uart also has all the correct output. But since I shut down once, I can't boot again.

The specific instructions are as follows:

SD card included: (sw6 mode: 1-4: on-off-off-off)

INIT_B is always red, DONE is always off, REST red is flashing off, PS_ERROR_STATIS and PS_ERROR_OUT are always off, uart has no output.

QSPI self-test mode: (sw6 mode: 1-4: on-off-on-on)

INIT_B is always red, DONE is always off, REST red is flashing off, PS_ERROR_STATIS and PS_ERROR_OUT are always off, uart has no output. (same as above)

Want to know if the board is broken, or need to use JTAG to re-firm the firmware or something? (There is currently no JTAG line), how to check the error? Please also enlighten me, thank you very much!

Have you tried to upload your image via JTAG? If this works then I suspect that you might have missed one of these steps:

1) Assigning the correct MIO pins (Vivado);

2) Preparing the First Stage Boot Loader (xsdk);

HI @hcyhanson 

Could you please try with this released prebuilt images, so that we can confirm that there is no issue in design side(software), then we can check hardware point of view :

https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18842543/Zynq+2018.2+Release

Please change the jumper settings as per SD boot mode(Table 2-4: Switch SW6 Configuration Option Settings):

Still if you see same issue even with prebuilt images, then please check this link for further debug:
