It booted OK.

Yes, E02 is already done.

I ordered the P22,
However, it contains a completely different E02, which makes it difficult.
It is impossible to return because it is overseas shopping. It is a pity.

Fortunately, it's the same as the V4, so it's easy to work with.
E02 boots well. The rescue system was also possible.

I hope Akitio is also possible easy, though.
OXNAS doesn't allow that easily.

Ah, it is sata boot from MyCloud Mini.

NAND boot not working...

Kang Jinsu,

I think you should temporarily ignore NAND for now. Just boot with HDD.

Your new NAND chip seems to be OK. But still there is something wrong that we cannot see.

I plan to rebuild a new SPL image to run in 700 Mhz (as stock does). Perhaps we will be able to see a little more with the new SPL. But I am not sure when I can get to that task.

Hello, I have also bricked my Akitio mycloud mini. I am an amature at figuring out hw to use jtag/uart/spi to flash my rom back to the tsop48 chip on the board. I have been using a raspberry pi pico with code installed on it from various githubs to try and figure out how to flash the nand. so far i have gotten the low hanging fruit and figured out how to hook up the pico to veiw the serial output in putty... this is what i used for code:
Uart Bridge

As I suspected, there is no image on the nand.

I was toying with using Pico Flasher and adapting it for my uses and flashing the NAND through SPI but i dont know what contact points to use (which i can probably figure out through the data sheet for the nand Hynix Datasheet) but where that plan falls apart is my lack of understanding of NAND chip timings and how the software needs to be augmented to be usable.

Finally, i looked into JTAG. I soldered headers on where "J10" is marked on the board and i am fairly certain it follows this convention Akition MyCloud Mini JTAG header and that led me to this git: JTAGenum which uses a rapberry pi (experimentally, which i have plenty of) to enumerate the jtag port and all its functions.

I have a serious lack of programming knowledge. I can solder and fix hardware, but anything software and how it all integrates and talks to each other i have a serious lack of understanding. (not for lack of trying though.)

If anyone would care to help/guide me on this last piece of what software/setup/ commands through, UART?SPI/JTAG, i can use to reflash my nand. I have original FW provided to me from AKITIO (apparently each FW is custom with each mac address added to the file). So if i can figure out how to flash the file I have, I think I will have a working mycloud again, not to mention the (intended) ability to run OpenWRT on the cloud device, as well as document the procedure and missing info on all Akitio Wiki's...

thanks for any help....

Drew,

I need the original FW to be the last resort to flash my nand.

I encountered the same problem as you. With the help of bodhi, I successfully installed Debian 12 from HDD and was able to start the machine, but I still want to know what happened to my Stock FW.

My Stock FW can start U-BOOT 1.1.2 and boot into uImage smoothly, but it cannot successfully mount ubi's rootfs. It is currently under comprehensive research, and this is an opportunity to enter this fascinating world of Embeded systems.

At present, I still encounter many problems, and I am working hard to acquire knowledge and slowly have all the concepts.

What you said about how to flash Stock FW to NAND in Linux system is completely achievable. Of course, you can also use U-BOOT.
Or, the JTAG method you mentioned. (This is also the method I have thought about and purchased J-FLASH related equipment.)

If you can provide STOCK FW, I would be very grateful.
