Hi @ll, I am moving the HTTPS App from the W7200 to the W5500 with a STM32F2xx MCU. And I am having a question regarding the code added by Gang 2011-9-27. while([color=#FF0000]FLASH_ErasePage/color!= FLASH_COMPLETE); As for the STM32F2xx MCU there is no FLASH_ErasePage. There is only a “FLASH_EraseSector” which needs a VoltageRange_? What is the correct VoltageRange needed for that? /* Program the network parameters received into STM32F1xx Flash */ //Added by Gang 2011-9-27 FLASH_Unlock(); //while(FLASH_ErasePage(FlashDestination)!= FLASH_COMPLETE); // FLASH_ErasePage for STM32F10x while(FLASH_EraseSector(FlashDestination, VoltageRange_1)!= FLASH_COMPLETE); // VoltageRange needed? while(FLASH_ProgramWord(FlashDestination, ChipID)!= FLASH_COMPLETE); if (*(u32*)FlashDestination != ChipID) { Sprintf(buffer, "%s","\r\n ChipID Flash writing error!!!"); }
