Subject: Re: [9front] UEFI boot on ARM / RPi
Date: Mon, 25 May 2020 08:49:41 +0200	[thread overview]
Message-ID: <CABDF7BED0C4652A6422EEB45014ADE3@felloff.net> (raw)
In-Reply-To: <CA+ULb+sQb78DejBGZY_vbFbubbKBik3Q9kQY5-mC5S21o32w5w@mail.gmail.com>

the raspi has two uarts! the uartmini and uartpl011. iirc, qemu
emulates the uartpl011. while in a real raspi, we use the mini
uart as primary. (they can be switched using gpio pin muxing).

i added a uartpl011 driver for the very reason so i could debug
in qemu (or early boot). try with console=1.
