[uClinux-dev] bootloader for MCF5234BCC

[Richard Cochran]

I am working with the very latest mainstream Linux kernel on the
Freescale MCF5234BCC. The kernel boots file (if I hack the root device
in drivers/mtd/maps/uclinux.c).

However, I am getting really tired of the dBUG thing. It only can
fetch an image via TFTP if I force the host NIC into 10 megabit mode.
I would really like to use a "real" bootloader, able to sent the
kernel command line, and working at 100 mbit Ethernet.

What can you recommend?

(It looks like u-boot does not directly support this CPU.)

Thanks,

Richard

To answer my own question, u-boot does in fact support this board with
M5235EVB_config. However, it did not compile at first because I was
using the compiler from the uClinux website, namely
m68k-uclinux-tools-20080626.sh.

This compiler is too old to compile the current u-boot, but the latest
Code Sourcery release does work fine.

Thanks,
