UART Serial connection

rctho
rctho over 3 years ago

Hello everyone. i'm hoping i can get some help with something i have been working off and on for a while. I have a SABRESD i.MX 6Dual/6Quad on a custom board from some OEM manufacturer. A few of them actually. I want to follow this tutorial to put linux on it. Looks pretty straight fwd. The problem i'm having is im unable to connect to the serial port to stop the U-Boot process if there is one at all. Currently there is Android on it so it's probably Fastboot. I'm guessing that the custom board does not allow a serial connection so it's not tampered with. I found what i think is a tx/rx on the board that connects to the chip for development.

 

 

Here is the pinout of the connection to the chip. the far left and right are vcc and ground while the two in the center connect to the chip.

 

and the headers i soldered onto it

 

Sorry for the noob questions. This is all very new to me and this is all i have managed to put together. If there is indeed Fastboot on it, is there a way i can flash U-boot without access to the serial connection that will later have a serial connection for me to connect to?

    your pictures don’t show. Can you try to edit your post, make a small change and save it again?

    That usually fixes it.

    Updated pics.

     

    on NXP someone suggested using the mfg-tool. I tried that with no luck because of version issues. There are a lot to go through. i'm pretty sure the one i have is the mx6DLL and might be a lil' old. I prefer the buildroot method. I was able to successfully boot to linux through usb, but unfortunately without a display so without the serial connection, i don't really know what's going on. In this time i have come across two more of these boards. If i can fig out one, i can use them all.
