Subject: [U-Boot] [PATCH] pico-imx7: Disable video support
Date: Sat, 23 Mar 2019 10:53:07 -0300 [thread overview]
Message-ID: <20190323135307.29439-1-festevam@gmail.com> (raw)
Since commit 9e3c0174da842 ("pico-imx7d: Add LCD support") loading U-Boot
via USB download mode causes the following hang:
SDP: initialize...
SDP: handle requests...
Downloading file of size 527088 to 0x877fffc0... done
Jumping to header at 0x877fffc0
Header Tag is not an IMX image
U-Boot 2019.04-rc4-00047-gcfb3e102c4 (Mar 23 2019 - 10:45:10 -0300)
CPU: Freescale i.MX7D rev1.2 1000 MHz (running at 792 MHz)
CPU: Commercial temperature grade (0C to 95C) at 40C
Reset cause: POR
Board: i.MX7D PICOSOM
I2C: ready
DRAM: 512 MiB
(Hangs here)
When booting from eMMC such hang does not happen and currently
we don't have a proper fix for this. Also, this hang in USB
download mode only happens with the older version of the
board that has 512MB of memory.
As a temporary workaround, remove video support so that users
do not have a negative experience in case they brick their board
and want to recover from USB.
We can re-add video support later when a proper fix is in place.
