When connected according to the datasheet, there is not even a read. And if the pins MOSI and MISO swap places, the chip returns 255. This is the default value. In the program you can see that I set the value to 0 and the return value to 255. So the reading is done. But the sector is not unlocked an...

Everything works in Proteus but not in hardware.
If connected according to the data sheet, the MISO and MOSI pins are reversed

Erasing does nothing!
Cleaning up didn't do anything either.
Made a write / read loop and the loop stops.
the program hangs. Recording doesn't work.
Only reading works.

Found my mistake, but the question remains...

Hello I use Atmega128 processor and AT25F4096 memory.
Writing to memory works correctly but reading always returns 1.

Thank you so much!!!!

Right!!!
Thanks a lot!!!

I do not know what to do...
How to return to the scene when did you work with the code?

Before using the Flowcode macros, the С code was written,
But after the use of macros Flowcode, the compiler began to issue an error!
As a result, neither macros do not work С code !!!
