I was working with the test code of QSPI. I generated the code using the latest STM CUBMX ver 1.10.1.
But after generation also it didn’t worked. Then I compared the code with the sample test code.
There I found the below mentioned code patch in the SystemClock_Config function.
Note : The activation of the I/O Compensation Cell is recommended with communication interfaces (GPIO, SPI, FMC, QSPI ...) when operating at high frequencies(please refer to product datasheet)
The I/O Compensation Cell activation procedure requires :
- The activation of the CSI clock
- The activation of the SYSCFG clock
- Enabling the I/O Compensation Cell : setting bit[0] of register SYSCFG_CCCSR
*/
/*activate CSI clock mondatory for I/O Compensation Cell*/
__HAL_RCC_CSI_ENABLE() ;
/* Enable SYSCFG clock mondatory for I/O Compensation Cell */
__HAL_RCC_SYSCFG_CLK_ENABLE() ;
/* Enables the I/O Compensation Cell */
HAL_EnableCompensationCell();
After adding the above mentioned code the generated code worked as expected. But I wonder that this code is not generated by the code generator.
Since it is recommended as per the note mentioned above. I also tried to find as where we can change this setting but was not able to find the same.
Can anyone guide as to where this I/O compensation cell can be activated using the code generator.
