Picozed(JTAG boot and SDACARD boot)

Hi all,
I am using Picozed (XC7Z020-1CLG400) and ARCNET module (COM20022I3V).
Picozed connected to ARCNET module via FPGA.
 
Problem:
When using JTAG to download FPGA and program to board, ARCNET module initialized successfully.
With the FPGA and the program but using SDCARD to download, the ARCNET module does not initialize successfully.
I still have not figured out the error is due to FPGA, program or first stage boot loader.
 
Look forward to the help from everyone.

Hello ctbk,

Hello ctbk,

Do you encounter this same isse when you try to boot your application from QSPI?

Hello Josh,

Hello Josh,
I still not try to boot from QSPI because the target is to boot from sdcard

Hi Josh,

Hi Josh,
I have tried booting from QPSI and the result is same as SDCARD. ARCNET initialization failed.
