Hello,
I am running Android as guest hosted by a bare metal minimal hypervisor on a dual core cortex a15 target. The hypervisor sets ttyS0 as a serial console and Android sets ttyS1, while on the host I have only one physical serial port ttyUSB0. What should I do to see the output on the host console? should I resort to any kind of serial emulator, virtual com port? Any advice please?
Many thanks.
I do not exactly understand your question ... What do you look to do?
At first, I just feel that this is a configuration problem .
OK, please let me reformulate/restate the question
- The serial console for UART host based debugging is initialized and prepared by u-boot, is it necessary for the kernel (or any other baremetal code) to reinitialize the UART? what minimum code needs to be added to the software layer (that u-boot gives control to) so that this layer can use the UART debug functionality?
Best regards,
