I had everything working including rescue boot. ![]() (ps, why did it get erased, well, mea culpa as i was playing w/ the partitioning w/ my own uImage :) in all cases, when i apply power, nothing happens until i kwboot it. I've also tried writing it back in using linux (both the mfg uImage and my own). I've tried writing the u-boot back in using both itself (booted from kwboot) w/ nand write.e 0 0 0x80000 (after loading it w/ tftpboot 0). The system has a single nand device (512M). If i boot it w/ kwboot, i can save/restore environment variables from the other half of the space.ĭoes anyone have any suggestions why the board will not boot when this is programmed to flash, but will boot it from kwboot? I have read back out mtd0 after programming it, and all seems well. I have the original u-boot image (extracted from the mtd0) and can boot it from kwboot.īut, when i save the image into mtd0, it does not boot from it (nothing happens on the serial). dts file and used this to build a linux uImage, which boots successfully (I have not attempted to build u-boot w/ this yet tho). The board is capable of kwboot a u-boot image. ** File not found /boot/dts/ox820-pogoplug-pro.dtb ** Loading DTB /boot/dts/ox820-pogoplug-pro.dtb. Partition Map for USB device 0 - Partition Type: DOS Reset IDE: SATA PHY not ready for device 0 Quick question, is there a environment flag we have to set to boot from ext4? I can boot from ext2 and ext3 but ext4 fails: I really need advise where to look for clues and will be happy to share any progress which I will gain. At this moment I am bit lost where to look and what to change - not sure if this is a problem of U-Boot/Kernel NAND support or just NAND flash controller is not recognizing NAND chip and refuses to initialize it.įor convenience datasheets are attached. ![]() Tried to boot unit via kwboot with original u-boot and unit is booting from NAND, tried to flash Bodhi's 2017.05 U-boot + recovery kernel/rootfs on USB for Stora - same problem - it boots via serial, but not in standalone. I can flash it with orifginal firmware files (nand dumps without ECC and OOB), flashing ends without any errors and complaints, but after reboot unit is completely dead - no TTL output from U-boot, no lights, just a spinning fan. Symptoms - when I load via kwboot/TTL original u-boot dump, chip is recognized with correct size, page size, eraseblock and so on. On a paper both chips are similar and should be interchangeable, but when I replaced Samsung one with Spansion one problems began. Looked for compatible alternative and based on datasheets decided to order Cypress/Spansion S34ML02G100TFI000. After few days investigation found that Samsung NAND chips of this type are EOL and it's no more on table for selling. Symptoms were - no TTL output, no LED lights/blinks, only one chip was recognized only one time from U-Boot via kwboot, but as 1MB/4KB pagesize. ![]() tried to buy same Samsung K9F2G08U0C-SCB0 from Aliexpress - both 5 chips arrived DOA. Second unit had dead flash with almost no good cells left and producing ECC errors, so I decided to replace NAND chip. ![]() I got two units of Netgear Stora MS2110/2000 (same hardware, but 2110 are sold with 1TB drive inside). ![]()
