From 9587b0d61133c025d48ebf480aa021fc2fdd53a7 Mon Sep 17 00:00:00 2001 From: Bryan O'Donoghue Date: Fri, 12 Jan 2018 12:40:19 +0000 Subject: [PATCH] arm: imx: hab: Add hab_failsafe console command hab_failsafe when called puts the part into BootROM recovery mode. This will allow u-boot scripts to script the dropping down into recovery mode. => hab_failsafe Shows the i.MX7 appear as "hiddev0,hidraw5: USB HID v1.10 Device [Freescale SemiConductor Inc SP Blank ULT1] " in a Linux dmesg thus allowing download of a new image via the BootROM USB download protocol routine.
