As far as I know old u-boot is having difficulties with booting newer kernels.It's better to update it. Take a backup of NAND mtd partitions first (nanddump and nandwrite are your best friends). As far as you have bootable OS on NAND/USB/HDD you can revert to stock backup images even without TTL connection. If you kill u-boot, kwboot is your way to going back to stock or point zero, but youby Gitsov - uBoot
Bodhi, I know that it is a bit of bad question, but ... can I boot it from NAND? After NAND change I have roughly 440MB free space on NAND, so it sould be enough for bare minimum to boot in shell, create RAID, partition it, format it. Later with a (lot) of scripting your Debian rootfs can be "expanded" on a hard drives and to full blown Linux installation. Main idea behind this iby Gitsov - uBoot
Yes, it's booting. With some modifications, original firmware says that rootfs partition is nearly 500MB in size and have 240-250MB free space after original rootfs placement on it. Bad points is that I wasted 50€ in trial/error exercises, because lack of documentation regarding supported NAND architectures and sizes.by Gitsov - uBoot
It's a Netgear Stora MS2000/MS2110. It's booted via Serial/TTL with uboot.2017.07-tld-1.netgear_MS2110.mtd0.kwb and USB flash. Also it is worthy to check which board and revision you have - Stora have A0 and A1 revisions as far as I know. At least my "main, production" unit seems to be A0 and second one "for experiments" is A1. I did not managed to get working (andby Gitsov - Debian
Hello, Likely the culprit is this: For Large page devices (2 KB and over), the block size, pages per block number, and the technology used (cell type is MLC or SLC) are read at runtime using the READID command (in bytes 3 and 4). Every manufacturer have it's own ID for copyright protection purposes and I am suspecting that bootROM is checking it. Depending what is predefined it can rby Gitsov - uBoot
I tried that already yesterday - nandflash just writes sectors from 0x0 to 0x100000 and no other errors are logged. This is for original mtd0 image, same for your u-boot, but addresses are less. If I flash env image it's freezing when original flash chip is used (it's 1MB is still alive), while Linux is booting, but have TTL output. Problem is when I flash either your u-boot or origby Gitsov - uBoot
It's booting. Log is provided in other Debian thread and it is attached here as well. If I need to keep PC near to NAS to keep it booting via serial ... I will throw unit in trash bin and will install some NAS software on PC (OMV, FreeNAS, Nas4Free, vanilla FreeBSD with needed packages) :) Goal is to make unit to be standalone and boot from flash (later will decide about SATA or USB roby Gitsov - uBoot
It's booting. I did not tried to resolve problem with environment variable space as for now I do not plan to use it on production. Mainly I am using it for flashing experiments with NAND. Boot log is attached in case it is needed. Let me know if it is required more commands to be issued.by Gitsov - Debian
Not sure that it is exactly 100% clone, as board model number is a different I think. Tomorrow I can check on Stora what was model number exactly, but this Medion looks very similar to Stora's hardware. At least with kwbooted U-boot Stora boots Debian recovery distro from flash.by Gitsov - Debian
Hello, I got two units of Netgear Stora MS2110/2000 (same hardware, but 2110 are sold with 1TB drive inside). Second unit had dead flash with almost no good cells left and producing ECC errors, so I decided to replace NAND chip. And now story begins: - tried to buy same Samsung K9F2G08U0C-SCB0 from Aliexpress - both 5 chips arrived DOA. Symptoms were - no TTL output, no LED lights/blinks, onlby Gitsov - uBoot
Hi guys, Sorry that I am hijacking conversation from nowhere. Seems that this is a "stepbrother" of my Netgear Stora MS2110. If you still need source code it can be easily obtained from Netgear opensource site and there is source tarball for MS2110 (newest one is unavailable): https://www.downloads.netgear.com/files/ReadyNAS/stora_source_2.3.2.tar.bz2 There is separate tarballby Gitsov - Debian
