Care to point me where you read this? It should work with all 5 control boards. Install method is Braiins Toolbox.Nvm i see the issue with the academy... just try it. S19 90 is not the same as the original S19, its basically an S19j, so it does NOT require the Zynq due to not using the bm1398, it has the bm1362 which IS compatible with bbb, aml, cv and bcb.
Thank Bitmain for their trash model naming.
