No boot from SPI memory when JTAG connected

Jump to solution

Hi 

Using XC7A200T-1FBG676C with SPI flash memory MT25QL256ABA8ESF-0SIT

Could programm the memory, but when JTAG is connected can't boot from SPI memory. With Jtag unconnected boot is OK.

M0 is 1, M2 is 0, M1 is 0.

Hi @markge,

 

This is an expected behavior. The JTAG port is considered the master communication method (also for recovery purpose), so if the board detects that a JTAG connection exists, it will interrupt any other configuration process and fall back to JTAG.

Please take a look at the following AR for instructions on how to overcome this issue:
