Re: UART Boot DNS-320 B1 with broken NAND - 5 years ago
Got another Dump of 768K. Named it mtd0.dns-320l. kwbooting works fine like usual. But no self booting from NAND :( root@debian:/dns-320l/uboot# kwboot -t -B 115200 /dev/ttyUSB0 -b mtd0.dns-320l -p Sending boot message.

Re: UART Boot DNS-320 B1 with broken NAND - 5 years ago
But the original mtd0 Partition size was 1M. So the "old" dump was 1M too. Should ist have been smaller without OOB and ECC? I recently modified the mtd0 Dump so ist loads faster through kwboot. ( Saved it under another name, and it is only 462K in size. Deleted nearly the whole FF Part from the middle to the end with a Hex Editor. )by Ironaxe - uBoot

Re: UART Boot DNS-320 B1 with broken NAND - 5 years ago
Maybe the best thing would be to bypass the NAND. But the question is if it is possible on this Box. It would be allso a great sollution for the other Box without NAND.by Ironaxe - uBoot

Re: UART Boot DNS-320 B1 with broken NAND - 5 years ago
Ok. Don't know how this came there ^^ Its working so far, the only thing left to do ( besides from more tinkering ;) ) is to get the Box to boot on its own. Booting via kwboot works fine. If i dont interrupt U-Boot it boots the Kernel from USB ( even from NAND, so the NAND should be OK ) but it refuses to boot on its own :(by Ironaxe - uBoot

Re: UART Boot DNS-320 B1 with broken NAND - 5 years ago
Ok, when i boot up the USB Stick e.g. bootm ......... and have a HDD attached the Stick changes form sda1 to sdb1 and hence it wont boot right. maybe with 2 HDD´s it changes to sdc1 ? Normally you would have 1 or 2 HDD´s installed but if not it does not boot ? One Step after another ^^ Marvell>> bootm 0x800000 0x2100000 ## Booting image at 00800000 ...

Re: UART Boot DNS-320 B1 with broken NAND - 5 years ago
Yep. The Power LED starts blinking while booting and stays solid when the system is up. I´ll try to test it :) Next thing would be to get the Box starting on its own without kwboot. Regarding the Power LED i found this The MCU D-Link put a small Microcontroller on /dev/ttyS1 at 115200 baud.
