Subject: [U-Boot] how to load u-boot environment from nand while spl is loading
Date: Wed, 11 Nov 2015 16:29:34 +0100 [thread overview]
Message-ID: <56435EDE.9070807@aethra.com> (raw)
I'm working with imx28evk reference board with u-boot 2011.12 and for my
specific purposes I have to load u-boot nand environment during spl
binary is loading. I'm working with a static environment but this is not
so useful because I need to initialize some drivers (such as serial
console) with the current values stored within nand flash environment
(such as baudrate variable).
Comparing my u-boot version with more recent ones (u-boot 2015.10) I've
found out that the enviroment loading has been applied during ram
bootstrapping...can't we do this operation before u-boot.bin has been
loaded in ddr memory?
Could you send me any tips to solve this issue?
