Hi,
What happens to PSoC4 if RS-232 serial cable is unplugged during a bootlodable update by the bootloader via UART? Does the bootloader keep waiting for the next UART reception?
Since it's only halfway written to Flash, it may lead to corruption of the bootlodable. But if PSoC4 is reset and the Host System sends the bootloadable image again, I think it's possible to update the bootloadable.
Best regards

Hi Alakananda,
Thank you for the answer. I understand the expected behavior of the bootloader. I think that's an irregular state when the serial cable is unplugged. Does the bootloader (software) have it as defined something like a state?
