Solve the problem by downloading an outdated version of armbian, armbian 20.05.4, it seems that the last version of armbian 20.08.1 works badly, when restarting it freezes and also the pin CS0 and CS1 are not activated, generating the communication problem by SPI, since the other pins are activated.
Anyway I hope someone will be of help to my solution, because it cost me time because I am a novice at this.
