Re: [U-Boot] u-boot 2018.07/2018.09 'data abort' kernel start failure with GCC 8.2.0 on sun8i (H3)

2018-08-25 Thread Auston Stewart
I wanted to update the list with the latest findings from the Sunxi Linux community regarding the data abort when loading the kernel. Although early testing implicated recent GCC, more focused testing has identified binutils 2.31 as the culprit and a specific commit causing the u-boot regression.

Apologies! I just realized I had my SD cards mixed up. 2018.05 compiled with GCC 8.2.0 isn't working either, although I just see a 'resetting' message rather than the full dump. The 2018.05 installation I saw booting successfully was compiled using earlier GCC. On Tue, Aug 21, 2018 at 3:17 PM

I tested another configuration to further isolate the issue: u-boot 2018.05 / nanopi_neo_defconfig / GCC 8.2.0 + Linux 4.17.14 / GCC 8.2.0 = works So something introduced between 2018.05 GA and 2018.07 GA associated with Sunxi H3 configs is rubbing GCC 8.2.0 the wrong way. On Tue, Aug 21, 2018

Greetings, As others have reported ( https://lists.denx.de/pipermail/u-boot/2018-July/334126.html), a 'data abort' occurs when attempting to load the kernel with recent u-boot compiled with recent GCC on Allwinner (Sunxi) H3 boards. I ran into this issue when performing a bootstrap of Shedbuilt
