I post a message here because I bought a TB-96AI recently with a carrier board, but I have a problem to make it works.
I was making a PCB for test it, but I was unable to power up the board.
Base on the carrier board and the SOM schematics I connect all the “VCC5
V0_SYS_S3” on my 5V power input, All GND pins to the ground and a button to “PWRON” to power on the RK809. But nothing happens. Does anyone know which pin is mandatory to wire to power up the board? Any document maybe?
I have seen on the carrier board schematics some pin (BOOT_CS1 for example) that are not present/connected with the TB-96AI or even on the TB-96AIOT. Maybe some of there pins are mandatory?
PS: I tried also to power up the TB-96AIOT but same story.
Thanks for your response.
