Hi, I met a problem when using JFFS2/MTD with Intel CFI Flash.I mount JFFS2 fs on a MTD partition and copy a file to JFFS2 fs, then umount the JFFS2 fs and reboot the system. The bootloader(PPCBoot) crashes around the first instruction. I check the Flash with BDI, and find the Flash in the Status state(i.e. 0x00800080). The Intel CFI Flash is supported in file cfi_cmdset_0001.c. After the read/write/erase operations, the Flash is not reset to Ready state(what I think is for increasing the performance). This doesn't happen with AMD CFI Flash(impled in cfi_cmdset_0002.c). Even the umount operation(with cfi_intelext_sync() called ) won't reset the Flash to Ready state. So run from Flash after reboot won't success except Hard reset.
I think the Flash should be reset to Ready state at least in cfi_intelext_sync(), which will be called whenever the MTD partition is closed. Maybe I have missed sth. Any ideas? Thanks. Shenrong ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
