Distinguish setup CubeMx for Keil

[A.Rade.96]

Hello my friends, why is not generated setup from CubeMx for my Keil, why is distinguish setup ?

In the register fields that control these timings, a value of 0 means 1 HCLK cycle, hence the difference of 1.

Except for MEMHOLD which is the same:

Thanks a lot, this is user manual cubemx?

This is from a reference manual for the STM32F4 series.

Thanks a lot to you help me, but i'm interested how to testing write and read my nand memory. My code is below this message, but me return always false.

oid NAND_WriteRead_Test(void)

{

  NAND_AddressTypeDef  page_address; 

  page_address.Block = 0;

page_address.Page = 0;

page_address.Plane = 0;

  // Filling the buffer with test data

  for (uint32_t i = 0; i < BUFFER_SIZE; i++)

  {

    write_buffer[i] = i % 256;

  }

  // Writing data to NAND memory

  HAL_NAND_Write_Page_8b(&hnand2, &page_address, write_buffer, BUFFER_SIZE);

  // Reading data from NAND memory

  HAL_NAND_Read_Page_8b(&hnand2, &page_address, read_buffer, BUFFER_SIZE);

  // Checking whether the entered and read data are the same

  if (memcmp(write_buffer, read_buffer, BUFFER_SIZE) == 0)

  {

    // The data was entered and read correctly

FlagNand = true;

  }

  else

  {

    // Errors when writing or reading data

   FlagNand = false;

  }

}

First thing to check would be to see if HAL_NAND_Write_Page_8b is returning an error code.

Note that last parameter to this function is the number of PAGES to write, not the number of BYTES.

Not return error, return HAL_OK for Write and Read return HAL_OK. Problem is arises to if loop is return else "FlagNand = false" . I don't understand why is false return!?
