Hi
I would like to change the firmware of the Crazyradio PA. However, Actually I just want to change the stuff that is sent. Mainly because I don't use much more control parameters that are sent. Is there an option to change the Crazyradio Firmware and flash it again? I would like to keep a USB-Bootloader in order not to be forced to use SPI to flash the nRF24LU1+.

Thx in advance

Hi,

You can flash a modified crazyradio firmware via USB the trick is that the bootloader is launched by the firmware so if you flash a bugged firmware you might have to recover Crazyradio with an SPI programmer.

On the latest git commits I added to the startup code a check for a GPIO so a simple bridge forces the crazyradio to bootloader, this makes it slightly safer but the master branch is still very bugged.

What I do is to work with USB bootloader but I always have an SPI programmer (a busblaster that I can use with nrfprog) in case I cannot access the bootloader anymore.

Regards.
