The full name of the memory chip is W25Q256JV. There are 6 options for the W25Q256xxx series. They differ in body, set of commands, and the number of control registers. You need to find documentation for the full name of your chip, without abbreviations. It is very important!!!
The W25Q256xxx series has shadow registers that load their value from one-time memory. Disposable memory can only be programmed once. For example permanently enable mode 4 data lines. Shadow register writes work in the same way as flash memory writes, the difference is in the speed of completion of the operation.
Shadow registers are not reset by a software reset, just like a hard reset - only by turning off the power. The control registers are loaded from the shadow ones during software and hardware resets, they can also be programmed an unlimited number of times - this is a simple memory with a flash memory interface.
W25Q256xxx will work well if you do not use all the features that the manufacturer has provided. Use only what is required at the moment. Otherwise, it may turn out to be a brick, with a gilded interface for a fixed frequency - for example, to load the firmware of an FPGA chip.
Line of code:
gpio_one_pin(zap_gpio.B.pin02.v_af09_quadspi_clk.speed4.pull_down.lock_on);
My personal bicycle will not work for the stm32h series - there are differences. You will have to replace these lines with your bike (with square wheels).
I'm interested in what you got.
