Hi Ted,

Your patch works! The m5329.c compiled.
But I got 2 additional undefined errors ref to nand_ecc.c, so I
corrected by adding MTD_NAND_ECC to linux config:
# Disk-On-Chip Device Drivers
#
CONFIG_MTD_NAND_ECC=y
CONFIG_MTD_NAND_M5329=y
CONFIG_MTD_NAND=y
CONFIG_MTD_NAND_IDS=y
And I added these two lines to
uClinux-dist/vendors/Freescale/M5329EVB/Makefile (as I did to make
uClinux-dist-20080808 work)
mtd0,c,90,0 mtd1,c,90,2 mtd2,c,90,4 \
mtdblock0,b,31,0 mtdblock1,b,31,1 mtdblock2,b,31,2 \
The image.bin was succesfully built. However, the problem now is the
image.bin booting has stopped at 0x000000000000-0x00000016e000 : "ROMfs"
(see captured display below)
I noticed differences between 2015 and 2008:
(1) Is m53xx compatible to m532x? [2015] uClinux/COLDFIRE(m53xx) vs
[2008] uClinux/COLDFIRE(m532x)
Yes, that is the intention. 53xx is meant to cater for similar
parts such as the 5329 and 537x families.
(2) Why different sizes for RAM probe? [2015] uclinux[mtd]: probe
address=0x4029bc20 size=0x16e000 vs [2008] uclinux[mtd]: RAM probe
address=0x401c83b8 size=0x3f7000
How big is your images/romfs.img file?
This size should match that (rounded to 4k I think).
Perhaps the default user space tool set is quite different,
thus producing a quite different size romfs (root filesystem).
(3) Why does 2015 not display NAND found like in 2008? [2008] NAND
device: Manufacturer ID: 0x20, Chip ID: 0x73 (ST Micro NAND 16MiB 3,3V
8-bit)
My first guess is that this probing is where the kernel is stuck.
So without the nand enabled do you get a complete all the way up boot
of 20150808?
(3) MTD partition creation? [2015] Creating 1 MTD partitions on "ram":
0x000000000000-0x00000016e000 : "ROMfs" vs [2008] Creating 1 MTD
partitions on "NAND 16MiB 3,3V 8-bit": 0x00000000-0x01000000 : "M5329
flash partition 1"
Any clues to solve this?
I would suggest adding some more printk trace in the m5239.c nand
driver to see where it is possibly getting stuck.
Regards
Greg

This really makes no sense. And it seems unnecessary given the
original poster was clearly already compiling the driver in
the kernel tree. The m5329.c driver source in that tree is
broken - the compile error messages give that.
You don't add *.c or *.o names into a Kconfig. They would only
ever go into a Makefile.
