Re: flash_query throws an exception (Redboot_ROM version)


Hi Mark,

Yes, I've kept the exact same settings for IXDP425_EXP_CS0_INIT


// CS0 (flash optimum timing) #define IXP425_EXP_CS0_INIT \ (EXP_ADDR_T(3) | EXP_SETUP_T(3) | EXP_STROBE_T(15) | EXP_HOLD_T(3) | \ EXP_RECOVERY_T(15) | EXP_SZ_16M | EXP_WR_EN | EXP_BYTE_RD16 | EXP_CS_EN)

I'm going to start with a clean anon cvs installation and start over.

Thanks!

Krishna

Hello Andrew.

Thanks for the response.

Yes 0x50000000 is the beginning of the FLASH - through gdb and through
BDI2000's telnet client, I can dump the flash at 0x50000000 and view the
contents.


This sounds like a bus configuration problem. I take it that this is a custom board. Is the EXP_WR_EN bit turned on for the CS0 config register?
