AM335x Linux SDK configuration

Bababeyk HamidReza

I have a custom AM335x board. I have TI PinMux output files for my custom board (mux.h , pinmux.h) . But in new linux BSP provided by TI (version 2.0 and 3.0)

the kernel support device tree for peripheral configuration. Is it necessary to port these 2 file to U-Boot source again?

also,

The default make configuration for kernel is tisdk_am335x-evm_defconfig ,but our platform is based on BeagleBone Black with a few change(Wifi instead of LAN)

we must use new configuration file or configure with menuconfig. In addition to these changes(1: DTS compile, 2: configure make) is it necessary to other change in source files , for example in board.c or spl.c?

Hi Bababeyk,

which version of Pinmux Tool do you use? The mux.h and pinmux.h files are generated by older versions. You can use v4:
processors.wiki.ti.com/.../TI_PinMux_Tool_v4
it has also web based version here:
http://dev.ti.com/pinmux

This version generates different than mux.h and pinmux.h files. There is explanation how to use them:
e2e.ti.com/.../1914100

About tisdk_am335x-evm_defconfig I can suggest to copy this file under new name and make your change in the new file.

Regards,
Yordan

Hi Yordan
The structure of mux.c in U-Boot source of TI SDK is totally different from am335x_gpevm_pinmux_data.c that produced
by PINMUX V4. How can I apply changes to mux.c file. if I want tor replace and rename that file to mux.c there is 2 header
file missing. types.h and pinmux.h.

Thank

Hi,

unfortunately the files generated by Pinmux tool can not be used directly in the U-boot (they are for StarterWare). You must use the generated am335x_gpevm_pinmux_data.c as a reference for the changes you need to do in "struct module_pin_mux" structures in mux.c

Yordan
