Hi everyone,
Firstly, I am sorry about my english! Thank you very much!
I have just bought a hantek DSO1062B with hardware version and serial number as below picture
I made a backup as instruction of Mr.Tinhead in this link:
https://www.eevblog.com/forum/testgear/hantek-tekway-dso-hack-get-200mhz-bw-for-free/msg86825/#msg86825Solder UART pin.
After made some stupid things, I have chosen wrong file to download to uboot in supervivi menu and the device could not boot again. Nothing shows on UART when the device turned on
I search in the internet, buy a J-Link and download supervivi to NAND flash through SDRam and the UART come back
I try to restore the backup which I have made from the begin but without success.
The backup in Tinhead's guide has only 3 files: boot.bin, kernel.bin and root.bin
But mine is 4 files: boot.bin, kernel.bin, root.bin and root2.bin
I try to combine them by this command:
copy /B boot.bin + blank.bin + kernel.bin + root.bin + root2.bin + mizi_tag.bin fw_backup.binBut the file "fw_backup.bin" is only
68.361.216 bytes while fw_backup.bin in TinHead's guide is
69.206.016 bytes, So the restore can not complete, it stands at 99% and can not boot too. (
https://www.eevblog.com/forum/testgear/hantek-tekway-dso-hack-get-200mhz-bw-for-free/msg75015/#msg75015)
When add more space to blank.bin file to get right size 69.206.016 bytes, the restore is completed but the device can not work too.
The problem is:
- How I combine the backup files to restore through supervivi
- Does anyone have backup bin file in 1 file only? Please send me.
- I have tried to write to NAND through openocd and J-Link but timeout, can not write 65.1MB to NAND
- How can I make the device work again?
I receive it in the morning and it stops working in the evening. It has been a week from now. I haven't used it to measure at least 1 time haha
Does anyone have any ideas? Please help me to solve this problem.
Thank you very much
I have tried to do a lot of things but no luck
