OSDN Handheld Months: Installing Linux on a Casio E105

Next, copy the config shown below to .config and run make menuconfig. You may need to change options If you're not using the same device.

Start the kernel compile by running make. While you're waiting visit ftp://ftp.ltc.com/pub/linux/mips/boot and grab the CyaCE boot-loader. In order to get the system to automatically run the boot-loader upon card insertion it needs to be named AutoRun.exe and placed in CE/R4100/on the card. You'll need to create a configuration file to go with it: The CyaCE config is named cyacecfg.txt and is also placed in the CE/R4100/ directory. The cyacecfg.txt is nothing more than the following:

By now the kernel compilation should be finished and you should have a vmlinux file in your kernel directory. Copy the vmlinux file to CE/R4100/on the compact flash. At this point you can verify that the kernel is compiled correctly and actually boots, you can accomplish this by hooking up a serial cable and running minicom. Set minicom to 9600 baud and insert the compact flash card. You should get the output shown below.

(If your CE device has an error message on screen with "unable to allocate heap" you'll need to perform a memory reset (hold down the power button and hit reset) and try inserting the card again.)
