Hello @andyp1per
I have four flight controllers, and I have checked all of them about the type of the MCUs
1 and 3
STM32F427 rev3(2MB) + STM32F100(crystal 24Mhz, flash 64KB)
2 and 4
STM32F427 rev3(2MB) + STM32F103(crystal 8Mhz, flash 128KB)
STM32F427 rev3(2MB) + STM32F103(crystal 24Mhz, flash 128KB)
updated:
double-check the crystal again and found it is 24Mhz NOT 8Mhz
I am using the fmuv3 image on them.

I have uploaded Pixhawk1 firmware to the site, it assumes 24Mhz crystal F100
Hello @andyp1per
That would be great, thank you.
I just download it and will test it ASAP.

What were the initial parameters used and how is the attitude control for that bear? 
The bear wants to fly but it’s too fat to fly.

I update my flight controller (4), and I got the following messages

Testing result 2 >>>>>>>>>>>>>>>>>>>>>>>>>>>>
The previous log was taken from the flight controller (4), IO is stm32f103, result failed.
I update the pixhawk1 image to the flight controller (1) it works. IO is stm32f100, result passed.

Thanks, it specifically will not work uploading the dshot firmware for f100 to an f103
CUAV v5 runs V4 firmware and cannot support dshot600, please help me to check him. pixhawk v6x works flawlessly.
Greetings. Trying to reverse channels on my Durandal and no success.
Motor 1 needs to change direction. When selecting motor 1 under blh_rvmask I reboot the fc and also do hard reboot of the esc’s but the direction does not change
Do you have SERVO_DSHOT_ESC set?
Evening Andy. let me have a look…
And you have BLHeli32 ESCs rather than BLHeli_S?
Just plugged motors back into AUX channel and assigned motors 9 to 12 and reversing works
Ok, thanks for the report - I’ll see if I can replicate
I also noticed that when the motors were connected to the IOMCU that blheli did not connect due to an error that stated that no active motors were connected.
You presumably have the safety button pressed? Did you check the motors turned?
yes that is correct.
Thanks for the report - it was a bug which I have fixed. I have put up a v5 in the same location - please test. Thanks!
