petalinux boot stuck at FSBL

Hello,

Zynq ultrascal+ is not booting into uboot , it is stuck at FSBL. Booted via QSPI Flash

I was able to flash new image to QSPI FLASH, but there wer some critical in Vivado 2018.2

CRITICAL WARNING: [Labtools 27-3421] xczu3_0 PL Power Status OFF, cannot connect PL TAP. Check POR_B signal.

Is this warning cause of booting problem, if yes how to resolve it.

 

Thanks & Regards,

Kayas

hi @kayas257 

1. In which line is FSBL hanged? Could you share the printed messages?

2. The critical says PL power status off, is your board succeful to bring up PL through other boot methods, like SD or JTAG?

Hi @kayas257 

 

I suspect PMU firmware issue.

Would you make sure PMU firmware version ?

 

If you use wrong firmware, it stack boot sequence.

Hello @watari ,

Thanks for reply.

 

It cannot be PMU firmware as same build works for other boards.
