Thanks a lot !

Can you now try to write on these images and read them ( and share them here) ?

EDIT : bitrate.zip removed !

SO: Save OK - Load&Verify:Fail
S1: Save OK - Load&Verify:Fail
S2: Save OK - Load&Verify:Fail
S3: Save OK - Load&Verify:Fail
S4: Save OK - Load&Verify:Fail
S5: Save OK - Load&Verify:Fail

Yup, here you are. Very similar result at my end

EDIT : S4toS7.zip & S0toS3.zip removed !

[Jeff]

Can write on this one and share it ?

EDIT : blank_S8.zip removed !

(I am preparing you a firmware with some debug stuff on the oled screen).

[hoby]

Here you are. The debug thing sounds interesting

EDIT : blank_S8.QD.zip removed !

[Jeff]

Here you are. The debug thing sounds interesting

Attached a firmware showing you on the first line how many times the write gate signal changed. First number : WG assertion, second number : WG deassertion.

Try to write on blank_S0.QD for example.
Should be "001 001" after a write attempt, but i think that we will have some surprises.

Change/eject the image to reset the counters.

EDIT : Removed !

[hoby]

S0 to S8: all have the result 001 001, so I guess it is how it should be.

all of them flipped the WG-assertion shortly after the "disk active" led light went on.

all of them flipped the WG-deassertion at the time when the "disk active" led light went out.
