Dear all,

Our amada pega357 turret punch machine with fanuc 04PC controller unable to boot.
I got this error "E04 C-memory access error" during startup.

I already tried to full reset the memory and replace the memory module MEM-A3 board but still not working.
Still stuck in the same error screen, unable to do other things.

I suspect the MMC board having problem but not really sure which one.

Anyone familiar with this error, please kindly guide.
