Coldfire M5485EVB with just released Linux kernel, u-boot problem

jkimble — Thu, 11 Sep 2008 19:56:19 GMT

I'm using a custom board based on the M5485EVB. Biggest difference is more SDRAM (128M) and more and different Flash (64MB, Intel P33).

I've made the same type changes I made to get colilo to work (Changes CFG_CS#_BASE, MASK and CTRL in M5485EVB.h and start addresses in start.S) but I'm getting nothing. Can someone tell me if there's a common way to change these two things (flash and ram size) in u-boot. U-boots a lot more complex than colilo so I'm just not sure if I'm getting everything that needs to change with a corresponding change to the CS0_BASE address.

Thanks,

U-boot is an open source project. Freescale does not own or provide direct support for u-boot.

That said, I found some info about porting u-boot to a new board:

A little Google goes a long way eh? I jumped too quick to the forum. There's a lot of stuff out there for u-boot (as opposed to the vast silence I found on Colilo)....

Thanks,
