Hi, <1> Recently I noticed the important of the Linker setting when I configured USB support(Someone say that need to increase the value in case of going wrong). So I am wondering how large I could set.How does it relate to System SRAM or somthing...

All data received in normal mode is 0, but some correct data can be received in debug mode？ cubemx configurations are as follows：Part of the code is as follows:uint8_t pData[128] = {0x00}; HAL_SPI_Receive_DMA(&hspi1,pData,128); while(HAL_SPI_GetStat...

CUBEMX Settings as above:The callback function is as follows：void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) { if(htim->Instance == TIM2) { LL_GPIO_TogglePin(CLK_GPIO_Port,CLK_Pin); } }The call code is as follows:USB_pri...

Got it.I should set Minimum Heap and Stack Size together 4KB at most,create a task with a hundred bytes at first and resize it by static stack analyzer.But I have a question where I could find the Linker settings in the Keil project? I get a projec...

Could I ask why it has to do with D-cache?

AASD.1 · 2023-06-09

Thanks you.it could recevie data normally after I remove SCB_EnableDCache().
