Hello everyone,
Using a custom board designed by myself, I can't manage to program the content of an S29GL064S NOR Flash. I'm pretty confident with the schematics and layout as, when calling the function
HAL_NOR_Read_ID(&hnor1, &NOR_Id)I get the following result
These values seem to match what's expected according to the NOR Flash datasheet (link here)
When I try to program the memory content using the small piece of code written here:
#define NOR_MEMORY_ADRESS1 ((uint32_t)0x60000000)
int main(void)
{
/* USER CODE BEGIN 1 */
uint32_t Address = 0;
uint16_t ReadData = 0;
uint32_t ii=0;
uint16_t WriteData =0;
uint16_t *pWriteData = &WriteData;
uint16_t *pReadData = &ReadData;
uint32_t *pAddress = &Address;

}When I run this piece of code, here are the results I'm getting:
For some reason, I seem to be getting the value of "ii" in each cell of my "Array" while that's obviously what's not requested in my code. I never manage to read back the value "0xbeef". I went through the content of the functions "HAL_NOR_Program" and "HAL_NOR_Read" and they seem to be pretty consistent with what's requested in the datasheet (Table 10.17 "Command Definitions").
I really tried to go to the bottom of this to make sure I did everything correctly before asking for help but I'm really lost here. Would anybody know what's wrong with my code and can help me fixing it?
Here is a print screen of my NOR Flash configuration in STM32CubeMX:
I hope it's clear enough, don't hesitate if you need more details.
Thanks in advance for your help!
