Hi all,
Just an update to this issue.
The problem has been resolved by disabling the alt_printf statement in my C code. My .pof works now, and it can send the spi commands after power cycling the board.

ContributorHi,
The start address on onchip_memory2_0.hex is based on the start address in Platform Designer system.
If it starts with 2000_0000, then it is mostly likely the OCRAM in Platform Designer starts from 0x2000_0000.
