how to flash new chip nRF51822 and STM32F405 in 2.1 brushless ?

[bitdeckai]

Hi,

Due to the incorrect input power supply, I suspect that my chip has been burnt out and I need to download the program again. How can I download new chip nRF51822 and STM32F405 in 2.1 brushless ?
Thanks!

Hi @bitdeckai !

If you want to get back to a working FW running on the Crazyflie. Set it in bootloader mode by pulling the power. Plug in the power while pushing the button on the front for at least 1,5 (but no more than 5 ) seconds.
To know that it is in the right mode, check the LEDS;
The blue LEDs should blink and the red LED should be off.

Now you can open the cfclient and flash the latest firmware by following this guide (https://www.bitcraze.io/documentation/repository/crazyflie-clients-python/master/userguides/recovery-mode/). Note that you need to change to the cfbl platform (radio button) when choosing the image to flash.

This should get your CF back to a working state.

I hope this helps you move forward with your issue.

Hi，ToveRumar：

In addition to firmware, there are also mbs, bootloader, how to download s130?

Hi @bitdeckai!
If you update through the client all of this is included in the package. You don't need to download anything.

You should be able to follow the instructions straight of the bat from your current state.

I hope this solves your issue!

Hi, ToveRumar:

I replaced a new chip with no program in it, so it cannot connect to the client

Hi!
If you think you might have burned the board, im afraid more components might be broken.

We could arrange a replacement for the PCBA since it is broken. Please send an email to contact@bitcraze.io and we can help you from there.

@bitdeckai Hello

I somehow got the same issue as yours but my IC pin was damaged so i simply replace the IC. Can you tell me how did you solve your issue with the blank nrf51822 chip
