Lamobo R1 serial console

Recommended Posts

Good day all.

 

Anyone having issues of not able to see anything after "Uncompressing Linux... done, booting the kernel." via serial console on Lamobo R1 ?

Tried to experiment a bit, it seems that U-Boot works correctly, but in Linux kernel, sent data from USB-serial to ttyS0 arriving correctly, but anything written to ttyS0 is not visible on connected USB-serial adapter.

Default kernel and boot parameters from image Armbian_5.00_Lamobo-r1_Ubuntu_trusty_4.4.1.zip.

Tried also to modify command line to include console=ttyS0,115200n8  - no difference.

Tried to manually in u-boot to specify different dtb (sun7i-a20-bananapi-r1.dtb) via setenv, still same behaivour of serial. only visible change was green activity led blinking.

Board boots, network works, but would like to get serial working as well.
