In application programming (IAP/USBx)

STM32CubeProgrammer supports IAP/USBx only with USB DFU connection mode. When USB connection is chosen and the boot is from flash memory, STM32CubeProgrammer detects IAP/USBx like a DFU bootloader, and after connection an IAP/USBx message appears in the log panel.

Note

Option byte, memory edition, and sector erase are not available with IAP/USBx.

Sample IAPs/USBx are available in CubeFW/CubeAzure on www.st.com.
