New Jetbot image, OLED does not work!

URGENT: I downloaded the newest Jetbot Image file for my class of 12 robots. Imaged as before, boots just fine, everything seems to be in place and functional, but the OLEDs are all dark and do not light up! These are the dual-camera Jetbots (1-2 years old) and swapping an older load, the display comes to life as normal. I tried several, the old load works fine. Is the current download not compatible?

Hi, exactly which robot kit are you using? Is it the SparkFun JetBot AI Kit v3.0 Powered by Jetson Nano? https://www.sparkfun.com/products/18486

They are v2.1, I didn’t realize it had changed so much! I was updating and now realize the v3.0 download is in no way compatible. At least it didn’t alter the boot loader like the new Jetracer software does, making it unable to boot the old SD card at all or use the processor on a Jetbot. I reflashed all the microSD cards from my last image and had everything working the next day. Since you have a few generations, you might want to consider obvious links for the image versions and caution users about getting the right one. Thanks
