Using the default env will get you closer to how most people will be using upstream u-boot, so running with the default env is preferred.

It still makes a lot of sense having a tool, which recovers as much of the 'dram_para' struct as possible. At least this can provide a way to verify the correctness of the sun8i dram code in u-boot, if compared with the same results obtained on a system with the allwinner boot0 bootloader. And also compared with the settings from FEX. Hans, do you remember your recent screw-up with the axp152 regulators? http://lists.denx.de/pipermail/u-boot/2014-October/191528.html You noticed the problem only several months after introducing this regression. This could be discovered because you were playing with the sunxi-3.4 kernel, and thankfully it was able to report the voltage, originally set by the bootloader. Had you thought about a way to test your axp152 tweaks at the time when you had initially implemented them, this regression could have been avoided altogether. Exactly the same applies here. The sun8i dram code contains some weird dram parameters scrambling before they are written to the registers among other things. How can we be sure that you have really correctly transplanted all of the boot0 logic into your C code without any typo or missing anything in the process? Especially considering that you are not disclosing any details about the way you have done this, or the exact boot0 binary that was used to borrow this logic from. Reading back from the hardware registers via /dev/mem and comparing this data with the expected values could definitely help. And no, it's not something that some other person could maybe do in some distant future. This is a necessary action to ensure the sun8i dram code quality, which is better to be done right now. -- Best regards, Siarhei Siamashka ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
