Failsafe booting to alternate linux image/fs

2020-05-28 Thread Brendan Simon (eTRIX)
Hi, Before I embark on my own implementation of a failsafe bootloading process from my embedded system (Xilinx Zynq board booting from SD Card), I thought I'd quickly ask the experts if there are any standard implementations in u-boot. The current u-boot being used is from 2015.  It probably need

[U-Boot] u-boot retries with fallback to other images

2015-12-06 Thread Brendan Simon (eTRIX)
Hi, Is there any documentation or u-boot support for having a list of boot images to try, starting with the first in the list, trying 1, 2 or 3 times, then trying the next in the list. e.g. boot kernel at mmcblk0p3, then mmcblk0p2, then mmcblk1p2, then tftp/nfs last resort fallback ? or boot

[U-Boot] fw_env.config settings for Digilent ZedBoard (Zynq 7020 Soc)

2015-12-06 Thread Brendan Simon (eTRIX)
Hi, I'm using a Digilent ZedBoard with a Xilinx Zynq 7020 SoC. The kernel is from Analog Devices and is a fork of 4.0.0 (according to the Makefile). I am struggling to work out the fw_env.config file required to use with fw_printenv/fw_saveenv. fw_printenv continually gives me CRC error and uses
