ASMedia ASM1153 Firmware Collection

I Decided to flash all of my old ASM1153's from Seagate Enclosures to the best firmware

which seems to be this as it's the most feature complete and the latest
141126_A1_EE_83 UASP + TRIM + Drive ID Passthrough

If you get problems with flashing failing you can either short pins 1+2 with small tweezers to boot into the safe rom
built into the chip,unshort when the pc makes the usb connected sound
or just unplug it and plug back in and try again

you have to be on the safe rom if you want to backup your current firmware

LED Normal = On when doing nothing
LED Reversed = Off when doing nothing

I have about 10 WD My Book Enclosures with ASM1151W's

You can pull up a leg of the SPI chip to boot from the Internal rom but there are issues the drive doesnt stop spinning when the pc is off etc

I Removed the SPI chip earlier and put it in my CH341A unprotected the chip then erased it

Flashed Seagate Expansion ASM1153 Full 64K firmware all worked fine ASM1151W was locked at Sata II 3Gbps
but apart from that all fine
Then Flashed one of the above firmwares USB ID was correct
instead of ID Passthrough it said ASM2115 in control panel
It was in bot instead of UASP
Trim wasnt showing
But it was at Sata III 6Gbps (370 MB/s With Bot)

as soon as you power the board on the spi chip is write protected again and you have to unprotect it if its put back in a programmer

I think the write protection is what's causing issues with the firmwares above and the reason nobody on the internet has managed to flash them
where as the Seagate Expansion is hard coded so doesnt need write access to the SPI

after about 10 chip removals trying different nvram settings to resolve it
no luck

think im just going to call it a day and Flash them all with Seagate Expansion ASM1153 Firmware

The two i have tested sofar are all Sata III capable so are ASM1153E's

If i had a no solder solution for chip removal im sure i could fix it
what really needs to be sorted is the write protection that is applied on the board's powerup
i tried disconnecting Pin3 it still got write protected

In your package there is a picture of the 'flash pinout'. But it is PY32F002AL15S6TU ARM microcontroller with 20kb memory.
The firmware files are 3 times bigger.

I don't have any WD enclosure but I can see on the pictures from the internet that there is only one flash memory chipset where can the firmware be stored - Winbond W25X20CL. It is 2Mbit=256kb size.

Flashing the mcu instead of the memory chip usually bricks devices but...
Some WD devices have self-repair function in their firmwares. When the memory of the microcontroler is erased, the device imediately reflashes it using 'the backup' of the program stored in the firmware. Unfortunately all unique values of mcu registers are replaced by 'universal ones'.
It is only my theory why those devices were able to work.

thats not my picture its just for the pinout for people take no notice of the model

Most of my devices are a Puya 512k nor flash spi chip
The wd's where Winbond W25X20CL
