Hi,
I have an issue booting the Davinci 8127 device. i m not able to figure out the mistake i m making. I have flashed the kernel image 'uImage' provided in IPNC RDK v3.0.0. Following commands were used:
TI8148_IPNC# tftp 0x81000000 uImage;
TI8148_IPNC# nand erase 0x00280000 0x00300000;
TI8148_IPNC# nand write.i 0x81000000 0x00280000 0x300000;
To flash the filesystem 'ubifs_ipnc_full_feature.bin' provided in the IPNC RDK v3.0.0, i used following commands:
TI8148_IPNC# nand scrub 0x006C0000 0xB940000
TI8148_IPNC# mw.b 0x81000000 0xFF 0x3400000
TI8148_IPNC# tftp 0x81000000 ubifs_ipnc.bin
TI8148_IPNC# nand erase 0x006C0000 0xB940000
TI8148_IPNC# nand write 0x81000000 0x006C0000 0x33A0000
Following bootargs were used:
bootargs=console=ttyO0,115200n8 rootwait=1 rw ubi.mtd=4,2048 rootfstype=ubifs root=ubi0:rootfs init=/init mem=80M vram=4M notifyk.vpssm3_sva=0xBFD00000 ip=134.202.84.79::134.202.84.245:255.255.255.0 eth=00.0C.0C.02.38.56 cmemk.phys_start=0x85000000 cmemk.phys_end=0x89000000 cmemk.allowOverlap=1 earlyprintk
Following bootcmd was used:
bootcmd=ipnc_ff_init 1;nboot 0x81000000 0 0x280000; bootm
Now when i boot the device for first time after flashing kernel and filesystem i get following 'Empty flash at 0x02367324 ends at 0x02367328' errors inifinitly. A snippet of bootlog is provided here:

If i reboot the device, i get 'Kernel Panic' message on this boot.
Sorry for such a long post but i tried to post the necessary info only. Thanks
