[Prism54-users] Big Endian xscale ( IXDP425 ) cross compiled Prism54GT driver issue

Mon May 16 10:49:55 UTC 2005

Dear List Members,

The cross compiled prism54 ( version 1.2 ) through up a "oops" like message and comes back to shell prompt if i bring up the interface by "ifconfig eth0 up" i use a XG-600 minipci card on a IXDP425 development board with uclinux kernel 2.4.24.

The same driver and the minipci card works well in a X86 based board 
Will this be a compilation issue or prism54 driver,Big-endian combination issue. 

I traced and found that the crash occurs in the file islpci_dev.c Exactly in the function 
isl_upload_firmware at the line __raw_writel(*fw_ptr, dev_fw_ptr);

Just before calling __raw_writel(*fw_ptr, dev_fw_ptr), i printed the values of *fw_ptr and dev_fw_ptr also fw_ptr and *fw_ptr are  c5d89000 905969898 dev_fw_ptr is 4bfff000

I've also pasted the logs and also the compilation logs for your reference. Thanks for any sort of help / hints on this issue.

John

The dmesg logs after i do "ifconfig eth0 up.
