imx6 solo kernel boot failed（gpu issue）

昌清黄 — Tue, 03 Feb 2015 09:25:13 GMT

Hi all：

The hardware board is our own development。（imx6 solo）

BSP ：L3.0.35_4.1.0_130816_source。 kernel defconfig：imx6s_defconfig

the project source code have not modified。

I compile the project after starting system：

MXC GPU has a bug？

how can i do？

Hi 昌清

you are right (refer to attached file)

and please use updated Linux BSP below

L3.0.101_4.1.1_SOURCE_BSP : i.MX 6Quad, i.MX 6Dual, i.MX 6DualLite, i.MX 6Solo

and i.MX 6Sololite Linux BSP Source Code Files.
