MSO5202D doesn't want to boot normally

xrayman

Hello everyone!

Back in 2014 I've bought Hantek MSO5202D; hw version: 1010×55778340; serial number: T 1G/012 019xxx. It has worked fine until recently. Then it started to boot once per 5-10 power-ups. I used it in such condition for some time. Then I had to switch power on and off like for a half an hour to get it booted up. And finally I've had enough and has started digging the information. First of all I connected to the oscilloscope using console port and obtained the boot logs - they're pretty much common for these kind of situations:

1. Warning - bad CRC or NAND, using default environment
   
2. 
   
3. 
   
4. 
   
5. ##### EmbedSky BIOS for SKY2416/TQ2416 #####
   
6. 
   
7. This Board: SDRAM is 64MB; LCD display size is: 800 X 480
   
8. 
   
9. Press Space key to Download Mode.!
   
10. SD:File System init failed!
    
11. Start Linux ...
    
12. 
    
13. NAND read: device 0 offset 0x300000, size 0x400000
    
14. 4194304 bytes read: OK
    
15. Boot with zImage
    
16. 
    
17. Starting kernel ...
    
18. 
    
19. Uncompressing Linux... done, booting the kernel.

Copy the Code

I contacted Hantek support via email describing the situation and they sent me firmware update files. I updated the system and it didn't help. Tried to contact support once again and have never received an answer. Then after some time of investigation I found dnw.exe utility and proper drivers for my device. Also somewhere on the Internet I found a link with dumps of the partitions from MSO5202D as it's stated in the title.
I ran the bootloader, selected the option `Test Linux Image (zImage)` and transfered kernel.bin from that link. And the oscilloscope booted up! Then I've reboot the bootloader and selected the option `Download Linux Kernel (zImage.bin) to Nand Flash` and transfered kernel.bin once again. Now I have the oscilloscope that boots up every time. The only issue is that those dumps are not for 5202D. Now in the System information I can see that the model is MSO5102B.

So the question is - could anyone please send me a dump of a kernel partition for MSO5202D?
My device has S3C2416 SoC and 4 partitions according to the boot logs (not 8). Boot logs of the oscilloscope before I downloaded the new kernel are attached.
