ADSP-21489 SPI boot after reset

Hello,

 

I've designed a custom board with ADSP-21489 with a M25P16 SPI flash for boot purposes. I'm configuring the .ldr to SPI flash , HEX and 8 bit. When I power on the board the boot is seems to work fine. The problem appears when I perform a reset. In this case the boot doesn't work and my system goes to limbo. My reset circuitry is the same used in the ADSP-21489 EZ-Board. I have double checked all the connection and everything seems to be fine.

 

Can anyone help me with this problem?

 

Best Regards,

 

Pedro Pinto
