Custom kernel compilation
« on: July 23, 2015, 02:32:51 PM »
Hi,

Iam using TC4.0 for the POS terminals that Iam working on. I need support for COM5 port for which I made changes to the below line items in the configuration item.
CONFIG_SERIAL_8250_NR_UART=6
CONFIG_SERIAL_8250_RUNTIME_UARTS=6

I followed the instructions on http://wiki.tinycorelinux.net/wiki:custom_kernel, till step #8 because all I needed was the kernel image.
I built the following version linux-3.0.21-patched.txz which I downloaded and did not apply any patches to it.

After I built the kernel bzImage (I tried giving "make vmlinuz " but it didnt allow me to). I booted my POS with the tinycore image and the bzImage that I built, the system halts when booting mid way.

Do I need to build the modules as well(building gave me compile errors -  saying XT_DSCP_MASK not defined ???) and use those, rather than using the tinycore.gz file?

Any help will be greatly appreciated. Thanks in advance folks.

If you built it on TC 4, and only changed those options, the compiler should match and there wouldn't be a need to rebuild modules. Where does it hang?
The only barriers that can stop you are the ones you create yourself.
