I tried firmware upgrade for RAK7200 using the RUI_RAK7200_V220.127.116.11_release.bin file.
But the STM32CubeProgrammer tool showed “Error: Operation exceeds memory limits” popup after erasing flash memory.
It seems that firmware file size(196640 bytes) on your web site is greater than the flash size of STM32L073 MCU which is 192 Kbytes.
Can anyone help this issue ?
