Adapter bga24 mach1 Winbond 25Q64FVBIG does not detect, help!

How many MACH1 do you have (and which PCB version)?

I don't know the problem, I dont have a PCB 2.0(only PCB 2.1 to test). I see no reason why the adapter should not work for PCB 2.0. But according to you, it works for PCB 2.1 but not 2.0.

So you can email contact@embeddedcomputers.net and mail/post the older units and get them upgraded to 2.1.

In the posted videos I tried 2 "pcb2.0" and they have the same error "Mode FWH returned ident code: 0x00002C00F1" and when taking out the adapter and putting it (without removing the bga-nand) to a pcb2.1 it detects me if problems.

You should see the problem, I don't think that both pcb2.0 are in trouble ... And also have to send the mach1 for the change, having to spend on shipping for an error that is potentially from the manufacturer.

If you are part of the staff, you should have equipment to prove the problem.

I will contact the mail, I hope you respond as soon as possible

Thank you!

BGA adapter was developed after PCB 2.1 was released. It was never tested or qualified with PCB 2.0.
The last 2 mach1 I bought were: the first one in June or July, I don't remember and it came to me in version pcb2.0 and the other one was in August, this one came in pcb2.1 ... (previously I bought other pcb2.0 when they were released in first quarter 2019).
About the bga adapters were already available, I saw them in June and nowhere is reference to their compatibility! ... "and in fact" were previously available for the other versions of fcusb

On PCB 2.0, check the VIO pin (in respect to ground) with a multimeter:
and tell me the value of the VIO
On what scale do I measure?
Do I measure with the bga adapter inserted?
Do I do it with the mach1 on or off?

Connect VIO to VCC (on MACH1 PCB 2.0). Then try.
I was already wrong to make the modification detects it! so as a summary it is not compatible with pcb´s lower than 2.1 ..

when reading I get mismatches when comparing with the modification, not when I use the pcb2.1 I get 100%.

probe la nand bga recording a backup made before with pcb2.1 on a device and this is not recognized by its emmc controller .. but when recording with pcb2.1 the same backup turns on without problems!

I will get in touch for the change and they should expose the non-compatibility because it lends itself to these problems!

That just appears to be ECC related. Not related to MACH1.

Only difference between PCB 2.0 and 2.1 is location of MEMS oscillator, and that PCB 2.1 has VIO pin which has separate supply for IO.
