what's the problem about the Edison console

Jump to solution

Hello everyone,

I designed my own expansion boar for Edison,and use the "FTDI FT232RQ" to change the UART2 as a console,when power my board and connect the console to my MAC,the address is :

/dev/cu.usbseriail-A504DYI7. I use screen command to get in ,there is nothing ,then I use the Arduino board the address is :

/dev/cu.usbserail-A502P3PQ and I can use the screen to get in. what's wrong? does it means something wrong with my own board?

Hello Teduav,

I checked the schematic of the Mini-Breakout Board and it seems to be the same as the one in your custom board, so as far as I can see, there are no issues with the connections. I suggest you to check if there is data flowing through the Tx and Rx pins of the FT232RQ to make sure that the USB-to-Serial section is working correctly. A logic analyzer would be great for this test because we would be able to see the signals and check if they are correct or not.

Regards,

Diego.
