POR boot

I have an interesting problem related to power up boot of a self made P2041 board.

I configured the chip to hard coded RCW that supports 16b NOR Flash (cfg_rcw_src[0:4] = 1_0010).

however, once POR signal is negated no FLASH chip select signal is asserted and the P2041 remains hang.

one can access its registers via JTAG debugger if needed.


any ideas why there's no chip select?
