- Thanks Jonathan for your reply,
I have follow you guidance. it improve the LCD touchsceen response. However, it's still hard to be used.
Do you have recommendation on capacitive touchscreen that supported by Critical link?

- No worries its a bit obscure. We should probably switch to documenting as 'source /usr/local/oecore-i686/environment-setup-armv5te-angstrom-linux-gnueabi' to make it more clear.

- Hi Mike,
Thanks for your response. After running the script, I tried typing "arm-", but it doesn't show me anything if I double press the Tab key.

- Hello,
[edited, you did run the setup script]
This command adds the path to the cross compiler tools to your shell. If you type "arm-" and hit the tab key twice you should see multiple gcc related commands appear after running th... - Hi,
I'm using MityDsp L138F, and I'm trying to load a simple program to the ARM core running Linux, as documented here: https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/Starter_Guide

- I found out that we cannot use the touchscreen whenever the mouse/keyboard is attached to the USB port.
after I plug off those, the touchscreen is working.
However, i got another issue, the ts_calibration is working with the followin...

Thank you so much. You've been very helpful. - JC 01:44 PM Software Development: RE: MityDSP L138F : The Linux kernel panics

ip=none should work. You don't have to configure the ip address at the kernel if you aren't booting from nfs. Note that i think your ip= syntax is wrong and it might be hanging while it tries to det... - OÇ 01:35 PM Software Development: RE: MityDSP L138F : The Linux kernel panics
- Hi, Bob,

You can prevent the kernel from waiting for a dhcp address by setting ip=none in the bootargs, though I noticed you set it to a static ip address this should prevent it from hanging as well. If its hangi... - JC 01:05 PM Software Development: RE: MityDSP L138F : The Linux kernel panics

Thanks for your help. I was following the instructions in https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/Linux_Kernel and I thought the "Root File System" article was the next step; that's why I tried boot...

Your bootargs tell the kernel to look at the on-board NAND flash for your filesystem. Is this your intent?
The kernel is crashing when it cannot mount the root filesystem on the NAND. Did you flash the filesystem onto t... - OÇ 07:11 AM Software Development: Additional details
