To: barebox@lists.infradead.org Both scenarios work well on another host. On my host serial port when interacting with one bootloader the communication is fine and with barebox fails. When using a USB-serial adapter there's no problem. Perhaps there's a problem on my board but why does the first connection work and with barebox doesn't ?
