Getting stuck when flashing Wifi Example on AI deck

[fairwel1]

Hi,
This problem has been bothering me for a long time, and I have tried but still cannot solve it. My steps are as follows:

I just follow the Getting started with the AI deck https://www.bitcraze.io/documentation/tutorials/getting-started-with-aideck/#flash-wifi-example

It looks like everything is ok when updateing Crazyflie and AIdeck firmware

And the OTA flashing stops at 3%. The crazyflie firstly restart after I enter cfloader command:
cfloader flash aideck_gap8_wifi_img_streamer_with_ap.bin deck-bcAI:gap8-fw -w radio://0/80/2M/E7E7E7E7E7
Then it will restart again about sevel seconds later.

I found my AI deck version is the older one(Rev.C1).I follow this step to flash the gap8 bootloader:https://www.bitcraze.io/documentation/tutorials/getting-started-with-aideck/#gap8-bootloader
And the output seems no error :

But I retry the step flashing wifi example and still stuck at 3%. There seems no changing that the Crazyfile behaves like the second step . Just restarting twice and hangs.

I find these similar problems mentioned before , but still couldn't slove it.

So what's the issues? Can you give me some helps?
Thanks!

Sorry to hear you are having problems flashing. Thanks for taking the time to investigate this and look into related discussions—it’s great that you’ve already gathered so much information.

Have you tried the resistor workaround mentioned in bitcraze/aideck-gap8-examples#105? Adding a 4.5 kΩ resistor between VCOM and ground can help drain the capacitor properly, ensuring the system shuts off cleanly and allowing the flashing to proceed.

Also, are you using any additional decks with the AI Deck? If so, try removing them during the flashing process. Lastly, make sure the AI Deck is securely mounted, with all pins properly aligned and fully inserted.

I only attach AI Deck on Crazyflie and never use any other additional decks. So "The lighthouse deck seems to add capacitance on VCOM, causing the GAP8 to not reset correctly" metioned might not be the cause the failure of flashing on my device?And also it seems hard for me to add 4.5 kΩ resistor without tools available.

I'm afraid we've also seen this problem, though to a lesser degree, with just the AI deck. Adding the resistor between the pins should be relatively easy. You can even just use clamping wires on the pins, use the breakout deck or solder between the two. An alternative is to turn off the copter for a few minutes to allow the charge to drain, before turning it on again and flashing
