Hi, is there an example of boot loader to be compiled using the GCC for Renesas compiler ?
I found one here RX113-Starter-Kit - Renesas Starter Kit for RX113 | Renesas
But it's using the default RX compiler which is not the one we need here.
Thanks
There was a very recent thread for RX660 that included a download for sample bootloader using GCC that should be applicable to your device.
