something wrong with the BusPirate4 to reprogram the cradio

[baicker]

i want to reprogram the chip nrf24lu1p with the bus pirate 4,
i connected the Bus Pirate and selftest with 0 error
then i connected the bus pirate with the crazyradio, and execute the command like this:

Code: Select all

zsh@zsh-ubuntu-pc:~/crazyflie$ sudo perl ./flash.pl -input ./cradio-0.52.bin -device /dev/ttyACM0 
Entering raw bitbang mode...
Entering binary SPI mode...
Configuring peripherals...
Configuring SPI...
Enabling programming...
Reading status byte...
Status: ff
Status isn't 0x20, write to device probably failed.  Check your connections. at ./flash.pl line 165.
Erasing chip...

then nothing happend.
are there anything wrong with my step ?

Hi baicker

I'am try to do the same. and i've the same issue.
i think that the issue could be the power because during flash.pl i see that v3.3 remain down.

i don't known the bus pirate v4.0 and then i can't modify the code correctly.
During this year have you found a right solution to going on?

I'll wait a your welcome reply.

thank you in advance.
