Ok first of all do not worry about it reporting the wrong type of OS as the build is in debug mode , so nothing to worry about there.

Now tell me the are you trying to write the same size file as the size of the chip ? or are you trying to write a smaller size ??

this is true .. FlashCat find AT45DB041 and Read chip "Atmel_AT45DB041_00-83FFF.bin"
later.. I changed all bytes 0x3712.png with Hex editor Neo.


write + verify programming ...

more time failed and 1,685Bytes/s

how 300.000Bytes/s ?
 
The 1.685 Bytes/s is the speed it is writing to the chip , read will always be faster , this should not be of concern at the moment.
I am not understanding what file you are trying to write to the chip , why are you editing the hex to 37 ?
 
I understanding .. ok .. 1.685Bytes/s .. 0x37 only for test. but I cant read again 0x37 .. always failed.
 
Do you have a file you wish to write to this specific chip ? if yes is it the same size as the chip size or are you trying to write to a specific sector on the chip ??
 
the chip have specific sector but I dont know for at45db series.. Can you practice with at45db?
 
I do not have any AT chips to look at , but if you are looking to write to a specific sector , you need to specify what sector you want to start at
 
Looking at previous screenshots , it already detects the chip , so i am afraid i do not understand what you are trying to do
 
I also meet little proble with AT45DB chips. The point is that default page size is not pow of 2. But with specific command it's possible to change page size to pow of 2. And with this page size Flashcat doesn't work properly.
I tested with AT45DB161D and AT45DB642D.
I have fix chip paremeters in source code, but I am not so close to VB and now my version works with chips with pow of 2 page size only.
To decide what is current page size we have to add additional read command.
Information about page size is avaliable in satus register.
D3mOn can you this feature in new release?
