Hi there
I am trying to upgrade our MTD/JFFS2 code(from October) to the latest CVS in the jffs2-2_4-branch and I think
something is broken in the MTD sublayer. Now MTD does not find my
second chip. This is the output from MTD before and after upgrade.
Before upgrade:
Lumentis: Found 2 x16 devices at 0x2000000 in 32-bit mode
0: offset=0x0,size=0x40000,blocks=128
1: offset=0x2000000,size=0x40000,blocks=128
Creating 5 MTD partitions on "Lumentis":
0x00000000-0x00040000 : "PPCBoot"
0x00040000-0x00080000 : "Environment"
0x00080000-0x00100000 : "FPGA"
0x00100000-0x001c0000 : "Kernel"
0x001c0000-0x04000000 : "JFFS2"
After upgrade:
Lumentis flash device: 4000000 at f0000000
map_priv_1 ioremaped to : c9000000
map_priv_2 ioremaped to : cd001000
0: offset=0x0,size=0x40000,blocks=128

PS.
Had to apply this patch to compile util/mkfs.jffs2:
