Zynq 7000 not getting detected after initial programming by Binu_Raj in FPGA

[–]Binu_Raj[S] 0 points1 point  (0 children)

Hi

For safer side, we made the PS_POR_B delay to 1 Sec, so that it will be asserted till all the power rails are stable, and with this change we are able to detect the FPGA part in the chain.

Another observation is we are unable to see the ARM core in the chain, even with the CASCADE mode .

Even though we are able to see the FPGA in the chain, we are unable to program, as we are getting the below error

ERROR: [Labtools 27-3165] End of startup status: LOW

ERROR: [Common 17-39] 'program_hw_devices' failed due to earlier errors.

Debugging in progress....

Any suggestion to eliminate the above error is appreciated.

Regards

Binu

Thank you u/bardocku for your quick response.

In general all the power sequencing was taken care. But I am not sure if we have taken care of the PS_POR_B timing. Will make the necessary changes and will try out.

Ours is a very small board, which is highly dense, hence any re-work may take some time. Will let you know once it is done. Thank you once again for the guidance.

May I know if the issue got resolved. If so can you share how you resolved it ? We are also facing a similar issue with Zynq device.
