FSMC_CLK is not running for muxed NOR configuration

Hi,

I am trying to configure STM32F207ZG nucleo board for synchronous muxed NOR flash and have configured for the same over cubeMX 

after generating the code i am calling HAL_NOR_Program and HAL_NOR_ReadBuffer in my code.

I probed FSMC_Clk signal but no trace of it on DSO.

Hi

Dhuri.Pranay

,

What about your initialization code and configuration?

Please share your .ioc file to check if you have correctly configured your project.

Thanks

I have attached .ioc file to the query now, please have a look.

Thanks.

Hi

Dhuri.Pranay

,

Your project worked great and FSMC_Clk signalappears for me.

Based on your configuration for

synchronous muxed NOR flash

, I just added read access in the While loop to the

BANK1

with address 0x60000000. Then the

FSMC_Clk

signal appears.

/* USER CODE BEGIN WHILE */

while (1) { /* USER CODE END WHILE */

/* USER CODE BEGIN 3 */

tmp = *(__IO uint16_t*) (0x60000000);

}

/* USER CODE END 3 */

}

Regards

Imen

‌,

I was callingHAL_NOR_ReadBufferto read in while loop ,the problem was with the address which I was using for read cycle. I was sending the address as 0x00000000, then I changed it to 0x60000000 as you said ,now I am able to see FSMC_CLK on LA.

Hi

DAHMEN.IMEN

‌,

For the same configuration(sync muxed NOR) I checked for write operation by runningHAL_NOR_Program()in while loop.

uint32_t addr= 0x60000000;

uint16_t data=0xEEEE;

while(1)

{

(HAL_NOR_Program(&hnor1,&addr, &data);

}

Then I probed AD[3:0] ,NOE ,NWE to check program but what I am getting is unexpected -

D7:- NWE

D6:- NL

D[0:3]:- AD[0:3]

here data(0xEEEE) is not as I am sending (for

AD[0:3] it should be E

)

but getting something different as output.
