ODI SFP DFP-34X-2C2 Does not start after applying new firmware

[lucioborges]

Checking the boot the UART Serial console, the system does not boot. Is there a way to perform a reimage xmodem? I can access U-boot terminal

MX25L6433F flash memory dump?

[Anime4000]

try setenv sw_active 0 and setenv sw_commit 0 ?

check printenv sw_active first see value is 0 or 1,

if output 0, set to 1,
if output 1, set to 0

[lucioborges]

I've already tried changing the system from 0 to 1 without success. I've already bought another SFP that should arrive this week!
For testing, I removed the MX25L6433F memory and am looking for an image of this memory to rewrite.
Thanks for the support. If I can solve it, I'll share it here.

[Anime4000]

Alright, if you managed to fix the MX25L6433F SPi Memory, the rootfs partition, share it, I'll link this from README.md

I wasn't successful in rewriting the chip, but I think I burned the power circuit of the old SFP by using my soldering iron on it, which isn't ideal. But I ended up copying a working image from my SFP OK, which is actually working.
But to rewrite the Chip you have to remove it from the board and use a CH341A reader/writer

If you need it, here is an image of the memory

Dont need to remove the flash ic, it can be programmed directly on the board!

[lucioborges]

With the memory soldered on the board, I was unable to read and write.

Maybe programmer not produce enough power

[Anime4000]

I have tried read SPI Flash direct from the board, thing is, the 3.3v is powering the stick when I start reading from CH341A

That time, my PON Stick still connected via UART, then I read the SPI Flash, cause PON Stick to power up and start booting

you can try read one, and verify multiple time, it will mismatch, so I end up need remove the SPI Flash off the board which is extra work to do

My programmer have power control feature, it's only enable 3.3V on operation (read, write, ...) it will block sfp from booting (maybe cpu cannot read spi flash and stop operation), I've read multi time, all CRC checksums are the same.
For other programer, you can try to connect power only when read/write,etc...

[Anime4000]

your Programmer much better than CH341a that I have.

May I know what programmer are you using?

does Programmer software has automatic SFP EEPROM Checksums?

It's Skypro II, like other programer, its only do checksum for whole dump file, for SFP, its have separate crc for config and info( PN, SN, mf date,...) (0x3f for config, 0x5f for info) and programer cannot calculate it automaticaly.

I see, this mean still need to use SFPTotal Wizard to for automatic SFP checksum.

I guess I try with my existing CH341a and IMSProg

after you show the EEPROM, now I confident and bought this for quick programming
