RE: u-boot or equivalent for MCF52223

Hi Rick,
I imagine that U--boot might be too big for the MCF52223 family's
on-chip memory of 256KB flash and 32KB RAM. But I do not know that fir
sure.
The dBUG ROM monitor is ported to the MCF5213 (same memory config) and
support s-record downloades.  You can prune it further to only support
the serial download and flash programming.

Subject: [ColdFire] u-boot or equivalent for MCF52223

Hi,

Can anyone direct me to an implementation of u-boot or an equivalent
boot
loader for the MCF52223?  Specifically I'm looking for some help
reprogramming the onboard flash through a serial port.  I'm currently
doing
this for a MCF5206e, but I load the whole flash image into external RAM
first.  The MCF52223 does not have an external bus, so no external RAM.
U-boot looks like an option, but I haven't found a port to this
processor.

Thanks,

Rick Cordray
