hello @And_Zammit if you're planning to train BERT models using Tinker Edge R, you will need to first convert BERT models to RKNN models(otherwise the NPU/AI accelerator will not work). here's a document for RKNN conversion https://github.com/rockchip-linux/rknn-toolkit/blob/master/doc/Rockchip_User_Guide_RKNN_Toolkit_V1.7.0_EN.pdf since each Tinker Edge R is an individual processing unit, you'll need an app to control from the host and switch between the boards.

hello @drluckyspin, those steps were correct, we'll need console logs to see what exactly went wrong; perhaps there's something wrong with image, please make sure that 1. .img file is in correct format, 2. the switches 1, 2, 3, 4 are: on, off, on, on, 3. after the switch adjustment, insert sdcard and power the board

First flash to emmc went fine issues flashing since
tooz replied to mikejbedford's topic in Software
2. I cannot figure out how to erase emmc or install a new version now that it is initially flashed. I can do all of the steps the same (going into mask rom mode) but the flash tool fails to flash anything any longer. @mikejbedford are you able to get your board boot successfully? if not, is there any error messages or logs? -

hello @kevco03, Tinker Edge R will fit your needs of using a 1080p USB webcam in YUV format. However, we'd suggest to use MIPI camera module for better performance.
