Issues installing Rockbox on HIFI Walker H2 v1.3

<< < (2/4) > >>

More information: Here's my nand info on my v1.3:


--- Code: ---readID opcode  = FF 9B 12 9B
readID address = 9B 12 9B 12
readID dummy   = 9B 12 9B 12
sfc params0  = 06 05 04 03
sfc params1  = 02 55 AA 55
sfc params2  = 00 5E 02 02
sfc params3  = A8 24 00 00

--- End code ---

I notice there's 3 bytes different in the sfc information...

And from my v1.6 unit:


--- Code: ---readID opcode  = FF EF AA 21
readID address = EF AA 21 00
readID dummy   = EF AA 21 00
sfc params0  = 06 05 04 03
sfc params1  = 02 55 AA 55
sfc params2  = 00 5E 02 02
sfc params3  = A8 24 00 00

--- End code ---

Ok, I would like to run a sanity check. Can you please use jztool to temporarily load this bootloader and then attempt to dump the flash info and the flash ONFI info?

Edit:

Here is also a shot-in-the-dark change to add more delay between resetting the nand chip and trying to identify it. Can you please do the same procedure with this as well?

I have ran the sanity_check_bootloader and got the following flash_info and again got the "NAND open failed" prompt, with an empty flash_onfi_info file.

--- Code: ---readID opcode  = FF E5 71 E5
readID address = E5 71 E5 71
readID dummy   = E5 71 E5 71
sfc params0  = 06 05 04 03
sfc params1  = 02 55 AA 55
sfc params2  = 00 6E 02 02
sfc params3  = A4 2F 00 00

--- End code ---

Same thing with the long_reset_delay_bootloader, got the following flash_info and the exact same problem with the flash_onfi_info file.

--- Code: ---readID opcode  = FF E5 71 E5
readID address = E5 71 E5 71
readID dummy   = E5 71 E5 71
sfc params0  = 06 05 04 03
sfc params1  = 02 55 AA 55
sfc params2  = 00 6E 02 02
sfc params3  = A4 2F 00 00

--- End code ---

Ok, no big surprise there but I had to try it. It appears that we can successfully read the flash when dumping the info, but we fail to correctly ID the chip for some reason. There are a couple of discrepancies between the two, maybe they are significant.

Let's do the same test with these two files:

second_read_bootloader.erosq: https://drive.google.com/file/d/1a5lfRcoPRjX4OtIImpP5uOjQCPLk64SP/view?usp=sharing
tsh0_bootloader.erosq: https://drive.google.com/file/d/1xbKolnWmISUpHl-XZVESQnx4_W-z3OuR/view?usp=sharing

Arrefur:
The flash_info files are the exact same, and the exact same problem with the flash_onfi_info file, with the "NAND open failed" prompt.
