Ye, I saw that at your Github fork. lwIP was Sascha's suggestion. Jules also has hacked a TCP stack into barebox. If we get an applicant, I will suggest they reach out to you. Are you on IRC btw? There's a matrix channel bridged there now, which you can use instead of setting up a bouncer. Cheers, Ahmad > >> +This project does not require dedicated hardware.
