Error scanning for deck memories
Hi!
I did some tests with my crazyflie 2.0 loaded with 10g extra weight. In the third run the CF flies into my safety net and crashes about 30cm down into the floor. After this crash the selftest of the CF won't work anymore and the M1 led blinks fast 5 times. I run it through the usb into the cfclient and got the messages in the picture. Apparently the there is something wrong with the "deck memories". What should I do? Is it possible to fix or do i need to replace something?
Thanks for answers!

Re: Error scanning for deck memories
Most likely something happened with the deck connector on either the CF2 or on the deck. The 1-wire memory is located on the deck so especially check the OW signal. See the pinout for signal location.

Re: Error scanning for deck memories
I have checked the continuity and that is ok.And I have checked the OW to ground signal and it is always about 13mV. What do you recommend to do? I need to find a good solution because I have some experiments left to do.

Hmmm, and if you don't have any deck connected you get the same error? Do you have any other deck to test with?

Re: Error scanning for deck memories
Yes, I get the same error both with and without my LOCO position deck.
Re: Error scanning for deck memories
Do you know how to compile and flash the firmware? If so could you build a debug build "make DEBUG=1 CLOAD=1" and flash it and post the cfclient console output here after connecting to it.
For simplicity I also attached the firmware here

Re: Error scanning for deck memories
This is the result of running with the new firmware. If it is the cfrazyflie that is broken is it possible to replace only like the motherbord of it or do i need to buy an entire new crazyflie? Since the motors seem to work fine.
Re: Error scanning for deck memories
Do you have the Crazyradio? Are you able to connect to it this way? Have you reflashed the nRF51?
You could turn of the OW functionality and force the deck driver instead but if the syslink (UART between nRF51 and STM32) is broken that wouldn't matter as radio will also be broken.

Re: Error scanning for deck memories
I have the radio but since the crasch I can not connect it to the cfclient, altough i can run the bootloader function by the radio. How do i reflash the nRF51?
Re: Error scanning for deck memories
If the bootloader works then the syslink should be intact.
Flash the latest firmware using the zip file and it should flash the nRF51 as well.
