I’ve been trying, for two days, and have been unsuccess in flashing a working SD card for the JetRacer. This image, jetcard_v0p0p0.img has been flashed several times, however connecting by a mini USB cable and putting 192.168.55.1:8888 in either Safari or Chrome on an iMac, nothing happens. This SD card works when flashed with Jetpack 4.4. I was able to successfully flash the image a couple months ago, put reused that card from something else. Any help would be appreciated.
