Hi Hans, I've built the latest sunxi-next branches of Linux and U-boot and tried it on my Q8 A23 tablet. My tablet has an OTG adapter with a USB ethernet adapter connected all the time. Upon booting into Linux I get an endless stream of: musb_bus_suspend 2586: trying to suspend as

Hi, I'm having some weird stability issues with my SinA33. After idling a while (a few hours ~ a day) it becomes non-responsive and just keeps outputting the same message: [53418.712180] Task dump for CPU 0: [53418.715403] cronR running 0 1131 1 0x0003 [53418.721780]

2015-09-29 Thread wens Tsai
Hi, I've been looking into AXP223 usage as part of the RSB patches. I found that the recommended voltage for VDD-SYS is 1.1V, but we default to 1.2V in U-boot. Among the fex files, some use 1.1V and some use 1.2V. Perhaps we could update the defconfigs with the values from the fex files. One

Hi, I'm seeing PMIC (AXP22x) init failures on my A33 boards. On my SinA33 it fails to set the RSB runtime address for the AXP223. As a result, the CPU is running at the default frequency of 408 MHz, instead of full speed. Wonder if anyone else is seeing these failures? Also I can't get my Q8H
