  • Try booting in different modes (like safe mode) to see if the DSI display works:

I edited the config.txt, added the command. dtoverlay=vc4-kms-dsi-7inch. This on windows. I removed the card and put it in rpi 4b, nothing happened. I removed the card, put it in the PC and the command disappeared. I reinserted the command, removed the card, reinserted it into the PC to check that it was recorded (yes it was) I inserted it back into the rpi 4b and again (nothing). I removed it from the rpi and put it on the PC. The command disappeared again. What do I do?

Sou novo por cá. E estou a utilizar o smartphone para fazer as perguntas.

Já consegui resolver uma parte do problema que é vizualizar no ecrã touch 7 polegadas . Mas há outro problema.

É que ao modificar o config.txt ele entra e consigo trabalhar com o PrimeOS 2.1.0 mas se reenicio já não dá porque o config.txt volta ao original, para conseguir entrar tenho sempre que configurar o ficheiro ( config.txt ). Porque isto acontece? Como posso definitivamente resolver este problema?
