Hi, yesterday I spent some time to get BareBox up and running on MPC5200B again. Finally I got it working on our hardware. Not yet tested for phytec pcm030, but I'm sure that without some fixes it won't work out of the box. I found and hacked/fixed the following problems so far: - cfi_flash driver has problems with big-endian. Some byte swapping is done in readb()/writeb() at HW access layer and also at several other places in the CFI driver. Swapping things twice isn't exactly what the driver and the flashdevice expects and needs a lot of more cleanups. - Detection of flash/bank layout was hacked to workaround 'faulty' values read from flash device (might be also a chip or HW design problem, I need to check that in more detail) - CFI flash buffer writes are broken with big-endian as well - Some problems and old bugs from the u-boot-v1 era found in cpu_init.c. Fortunately the HW did the right things although some register setups were broken. - Missing headers for arch/ppc to compile the liblzo code. (unsigned.h ?) Now with network, flash and basic debugging outputs available I would like to port some more drivers and at least RO filesystems (fat, jffs2, ext2/3/4) for MPC5xxx platform and replace the stone-age crappy u-boot asap. Just in case - Is there any on-going or even experimental work for MPC I could start with? -- Carsten Schlote <c.schlote@xxxxxxxxxxxxxx> konzeptpark.de _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
