Flash encryption to ESP32-C3 and JTAG flashing
Posted: Tue Jan 14, 2025 6:24 am
Hello,
I am interested in Flash encryption, and possibly subsequent JTAG programming.
How Flash encryption and JTAG programming are related?
I have a device made with ESP32_C3 MCU, I have no UART pins available, I use JTAG for programming/debug and for printing log messages. I need to somehow protect the ESP from illegal code acceptance, but also leave the possibility that it can be reprogrammed later after bugs are found. OTA has not been implemented yet
JTAG: Built-in USB SERIAL/JTAG interface is used (USB_D+ and USB_D-pins)
How to perform correctly? Thanks
