Hi, Is it possible to use the serial port for u-boot networking? For example, given a restricted environment where the FIT image is available with ethernet firmware and drivers, so it is not possible to boot it with DHCP boot since there is no networking. Or simply the ethernet NIC has no u-boot driver at all. For such cases, I assume ymodem is recommended to download and boot the FIT image.
However, experimenting with different images and debugging, it would be more convenient if serial could be used as both data and console channel. Is this possible? A simple example: 1. ppp on the host machine, with IP forward, NAT, etc. 2. u-boot establish a ppp connection over serial to the host 3. u-boot starts a netconsole session to the host 4. user can use netconsole and wget to download images I was thinking of PPP, but that's probably not supported by u-boot. Anything similar with RNDIS and USB CDC ACM? Thanks in advance for any hint! Best, Ferenc
