Hi there,
I want to use JFFS2 as root fs on a TQM860L board (with u-boot-0.3.0)
It has to flash banks:
Bank # 1: FUJITSU AM29LV160B (16 Mbit, bottom boot sect) Size: 4 MB in 35 Sectors Bank # 2: FUJITSU AM29LV160B (16 Mbit, bottom boot sect) Size: 4 MB in 35 Sectors
I added a "CFG_CMD_JFFS2" to the CONFIG_COMMANDS and the lines
#define CFG_JFFS2_FIRST_BANK 1 #define CFG_JFFS2_FIRST_SECTOR 0 #define CFG_JFFS2_NUM_BANKS 1
in ./include/configs/TQM860L.h.
But when building the binary I always get :
ppc_8xx-ld -Bstatic -T /home/scholz/Projekte/u-boot/board/tqm8xx/u-boot.lds -Ttext 0x40000000 -n cpu/mpc8xx/start.o \ --start-group board/tqm8xx/libtqm8xx.a cpu/mpc8xx/libmpc8xx.a lib_ppc/libppc.a fs/jffs2/libjffs2.a fs/fdos/libfdos.a net/libnet.a disk/libdisk.a rtc/librtc.a dtt/libdtt.a drivers/libdrivers.a post/libpost.a post/cpu/libcpu.a common/libcommon.a lib_generic/libgeneric.a --end-group \ -Map u-boot.map -o u-boot /home/scholz/Projekte/u-boot/board/tqm8xx/u-boot.lds:137 cannot move location counter backwards (from 40008124 to 40008000)
I tried different values for CFG_JFFS2_FIRST_BANK et.al. But I have to admit I am not sure about their meanings! ;-)
Is CFG_JFFS2_FIRST_BANK=1 the second bank? Is CFG_JFFS2_NUM_BANKS the number of banks used only for JFFS? Or the total number of flash banks?
On a different board (DAB4K, with only one big flash bank) I just had #define CFG_JFFS2_FIRST_BANK 0 #define CFG_JFFS2_FIRST_SECTOR 0 #define CFG_JFFS2_NUM_BANKS 1 and it worked.
How does the code find the JFFS partition? Just scanning the flash for a bit of magic? (0x1985?)
Thanks a million in advance!
