Asix causes to kernel panic on Android

mkurnaz · March 29, 2016, 02:34:14 PM

Hello All,

We have made a custom board like Olinuxino with NAND, 10"LCD and touch panel. We have build Android Jelly Bean, created sun5i_android_a13-evb.img. We have flashed to NAND. It looks good but after a few minutes, Asix driver gives error and causes kernel panic.
Kernel messages is like below;

We tested A13-Olinuxino board. Problem occurs on this board too. There should be anyone who encounter ASIX problem. It is about ASIX and memory usage.

Best regards

Is that driver standard with the Olimex A13 board, i.e. used by everyone?

John

mkurnaz · April 05, 2016, 11:27:41 AM

Yes, it is standard driver. It is /system/vendor/modules/asix.ko We tested with a13_android_sd_800x480_first_release.img. We changed only script.bin for VGA.

Best regards

I don't see it loaded / in use. Are you connecting some external hardware or what?

I don't recall a previous report like yours so anything non-standard about your Olimex A13 hardware or software?

John

mkurnaz · April 05, 2016, 12:06:17 PM

There is no any external hardware, only usb2eth converter. We mounted NAND for NAND iamges but we used a13_android_sd_800x480_first_release.img for SD card. And we only changed script.bin for VGA. We enabled eth in settings than surf the web with default android browser. Kernel crashes when surfing or when setting network. It seems about memory. I cat /proc/meminfo, and output is:

I'm lost. I simply cannot see the device. Is it a USB device you plug in?

I feel it cannot be because you would have said so and put the actual device full name / URL.

Hello John,
Firts of all, so thanks for your help.
We have A13-Olinuxino board and mounted NAND flash on it. But we tried SD card image a13_android_sd_800x480_first_release.img. We used for ethernet, usb device USB-ETHERNET-AX88772B.

If you ever post a new thread be sure to include ALL relevant data.

The product page says it's supported by Linux. You are using Android. So, up to you how you proceed - maybe debugging the Android driver yourself, contact the driver maintainer or choosing another device.
