orginal PA dongle firmware with USB bootloader

Post by jimmy_craze »

Hi, I accidentally erased the NRF24LU1+ chip on my pa dongle with this script ( ) provided in crazyradio wiki and now my chip have no bootloader in it :cry:
The script is meant to write a firmware which contains bootloader to the chip because it will first erase everything in that chip, but official crazyradio PA firmware I downloaded from github doesn't seem to have contained a bootloader.

I tried to flash official Nordic NRF24LU1+ bootloader using the script above, but it always crashed at address 7faa so I'm really stucked here.
Could any one kindly provide me with off-the-shelf crazyradio PA firmware which has the bootloader so I can rescue my dongle? :?

If writing the firmware does not work, writing the firmware and the bootloader will not work.

I have never managed to get the buspirate to work properly to flash the Crazyradio and I have never liked this script very much because it erases everything instead of erasing only the firmware, I added a warning in the wiki about this.

You can flash the bootloader using a Raspberry pi, there is some doc and script on how to do it there: viewtopic.php?f=8&t=2753&p=13808#p13890. The cabling is similar to the one described in this hackster project: ... -pi-08796b.

Out of curiosity, why did you reprogram the radio that way in the first place?
