About GUI_Init stuck when emwin is ported to stm32f2 [Copy link]

The program compiled and passed the simulation, but it got stuck at GUI_Init. It also couldn't jump to the stuck place when it stopped. The solutions on the Internet all said that CRC was not enabled or there was not enough memory. CRC has been turned on in stm32cubeMX. I also tried to add RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_CRC, ENABLE); to the program, but it prompted that the function was not defined. I defined it like this: void RCC_AHB1PeriphClockCmd(uint32_t RCC_AHB1Periph, FunctionalState NewState) { assert_param(IS_RCC_AHB1_PERIPH(RCC_AHB1Periph)); //Parameter correction assert_param(IS_FUNCTIONAL_STATE(NewState)); //Parameter verification if (NewState != DISABLE) { RCC->AHB1ENR |= RCC_AHB1Periph; //Open the corresponding peripheral clock output port} else { RCC->AHB1ENR &= ~RCC_AHB1Periph; //Close the corresponding peripheral clock output port} } Still stuck. As for the memory problem, I also opened the external memory on cubeMX (there is also an external memory on the board), and also tried to comment out the unused functions, but it didn't work. Please help me

Then try to see if the GUI initialization can pass. If it can't pass, see if the transplanted initialization code is normal. If you suspect that the RAM is not enough, first set the SIZE in the h file to a smaller size to find out the specific problem and then see how to fix it.

The OP must load the CRC library file of ST.

Is this the library?

Yes

1) It is recommended to generate lib from the library source file and load it into the project, which can save a lot of compilation time. 2) Generally, making an interface consumes more memory, so you can remove the unused things first and try it out.

To solve, I used the hal library but added the standard library function, and the problem was solved by replacing it with the hal library.

How did you solve this problem? You are using CubeMX, but why do you use the standard library? I also encountered the same GUI_INIT() stuck problem. Where did you use the standard library function? I also want to check mine.
