Hello, In fact relocating the whole file after the bad block was my first intention. I agree that proceeding this way wouldn't allow the TFTP update process to load up the min-sytem recovery environment. My thought was to launch it manually from u-boot. But finally when I realized that u-boot...

Hello, I DID RECOVER MY MIN-SYSTEM! :) As I've seen in the mtd8 images that there were a lot of spare space at the end of the partition and as the bad block in my cam was at the begining of the partition I first decided to relocate the useful data after the bad block and to boot manually to the...

Hello Alastair. Thanks again for your help. Without you I would not have been able to get my cam back! "Just for fun" :) now that the cam works, I'm wondering if I could get a recovery mode available. I see several potential options: Option 1: Find a way to "recover" mtdblock8. As far as I...

Than you! I'll have a try. Have a nice day.

5.4.5 upgrade works now!!! Time to sleep!...

YES! Modifing the u-boot bootargs parameter to start init=/bin/sh I could prevent the CAM from rebooting! HKVS # setenv bootargs console=ttyS0 initrd=0xc0a00000,0x400000 rw root=/dev/ram dbg=0 init=/bin/sh HKVS # boot Then launching all but the last line of /etc/init.d/rcS manually I've got...

Thanks! So let's get a try to option 2!...

Hello, Thank you for your help! I have the same results as you for commands "ubinfo" and "cat /proc/mtd" # ubinfo -a -d 1 ubi1 Volumes count: 1 Logical eraseblock size: 129024 bytes, 126.0 KiB Total amount of logical eraseblocks: 192 (24772608...

Here is the "dmesg" log: # dmesg dma_parse_error: fio dma read error 0x5000800. [ 134.924583] ambarella-nand ambarella-nand: nand_amb_request: cmd=0xe, addr_h! [ 134.924913] fio_dma_parse_error: fio dma read error 0x5000800. [ 134.924968] ambarella-nand ambarella-nand: nand_amb_request...

Hi, I've been able to mount a share from my NAS using the following sequence: # ifconfig eth0 192.168.0.20 # mkdir /mnt/tmp # mount -t cifs //MyNasIpAddr/MyShare /mnt/tmp -o username=MyUsername,password=MyPassword,iocharset=utf8,file_mode=0777,dir_mode=0777 I've saved the current state of mtd8...

Yes, I've noticed the filename was fogotten! ;-) I've tried with a SD Card formatted in FAT32. It doesn't seem to be available : # ls /dev amb_gadget loop5 mtd3 mtdblock5 tty14 tty39 tty63 ambac loop6 mtd3ro mtdblock6 tty15 tty4 tty7...

I think maybe I could use an SD card to exchange data with the CAM since I've got a shell now...

Hello Alastairs and Thank You for the reply! After my previous post I've tried the followin bootargs configuration bootargs=console=ttyS0 initrd=0xc0a00000,0x400000 rw root=/dev/ram dbg=0 init=/bin/sh It let me have a shell prompt but barely nothing functional. Then I've launched : #...
