kernel build how to in LTIB

garimella — Wed, 13 Jul 2016 08:28:10 GMT

I could port the linux kernel into MPC8309 custom board. Wish to write applications and also develop device driver. Not able to start it even with read me file. Practical advise will be appreciated.

NXP offers LTIB Linux BSP for the MPC8309KIT and for TWR-MPC8309 boards:

https://www.nxp.com/webapp/Download?colCode=MPC8309-KIT_Linux_BSP&appType=license&location=null&Parent_nodeId=1281540457516714915076&Parent_pageType=product

and

http://www.nxp.com/webapp/sps/download/license.jsp?colCode=TWRMPC8309_LINUX_BSP&location=null&fsrch=1&sr=2&pageNum=1&Parent_nodeId=&Parent_pageType=

Use this LTIB under Ubuntu 10.04 or 12.04.

See also Reference Manuals in these BSP.

Usually the following command sequence is used for kernel building under LTIB.

1. ./ltib – This command is used for LTIB building

2. ./ltib -m prep -p kernel - This command is used for getting kernel source.

Change the kernel configuration.

3. ./ltib -m scbuild -p kernel - This command is used for building the kernel.

4. ./ltib -m scdeploy -p kernel - This command provides deploying the kernel.

See please the following pages (http://www.bitshrine.org/autodocs/LtibFaq.html).

Have a great day,
Pavel Chubakov

Hi Pavel,

Yes I could do all the porting with the commands recommended by you in LTIB. Having some trouble with developing applications on the kernel. Since 2.6.34 is ported to MPC8309 board, I wish to run some simple applications beginning with hello world to writing some custom device drivers. Where to start. What commands in LITB will assist cross compilation for kernel applications and how to go about writing device drivers in LTIB environment?
