Hi, I made some progress. In summary (I'll post some details later): => I found an image built for rev.A instead of the required rev.B, which somehow boots - uart version doesn't boot - nand version (automatically patched by kwboot for uart booting) boots with a lot of errors like Bad block at 0x100000 in erase block from 0x100000 will be skipped and ends with the messageby romiz - Rescue System
Hi, after a very (very) long series of attempts I managed to transfer the image without errors. The culprit is the serial console service that interferes with the transfer. I'm on a Raspberry with plain Debian, and the solution is to stop "serial-getty" with: systemctl stop serial-getty@ttyAMA0.service Unfortunately, none of the images here https://downloads.lacie-nas.org/by romiz - Rescue System
Hi, bad news here, after 3 weeks: I think I'm REgressing. No matter what kind of cable or what's the distance from disturbing power sources, I cannot finish the transfer anymore. I also tried with different power units. I cycled through all the u-boot*.kwb I managed to get, but it invariably stops at ./kwboot_static_2024.04-rc3 -t -B 115200 /dev/ttyAMA0 -b u-boot-nas2big-revAby romiz - Rescue System
Thank you bodhi for the suggestion. I'm not there yet, even if the kwboot mechanism is actually working: I have a hit/miss ratio very low. The most difficult part is the uart cabling: I'm still struggling with wire length, wire shielding, distance from source of interference, etc. Sometimes I managed to reach the point 98 % [....................................by romiz - Rescue System
Hi everyone, I'm asking for help in de-bricking a Lacie 2Big NAS: I wiped the bootloader. I wonder if anyone of you could send a copy of the stock u-boot or a different but working version. I know that u-boot should be very board-specific and the device is exactly this as reported on lacie-nas.org (https://lacie-nas.org/doku.php?id=2big_nas). I don't know if the same u-boot can beby romiz - Rescue System
