Subject: [DistroKit] [PATCH] v8a: barebox: add missing defaultenv directory for MMC boot
Date: Wed, 13 Jul 2022 10:45:55 +0200 [thread overview]
Message-ID: <20220713084555.3371718-1-j.zink@pengutronix.de> (raw)
MMC images generated by DistroKit for i.MX8M family of EVK boards did
not boot beyond bootloader shell without manual intervention, because
there was no environment compiled in telling barebox where to load the
kernel from. Add this missing environment, so we can boot directly to
userspace shell with DistroKit-generated i.MX8M SD-Card images.
Fixes: f1d8cd1 ("Add barebox for i.MX8M boards")
