TDA2HG: pin mux set in uboot

terence xia

Part Number: TDA2HG

Hello,

According to genericFileFormatPadConf.txt from TI pinmux tool, we are ready to set pin mux in the u-boot/board/ti/dra7xx/mux_data.h. While, how do we do? For example, below is mmc1 in genericFileFormatPadConf.txt, how do we modify in u-boot/board/ti/dra7xx/mux_data.h?

==================================================================

0x4A003754 0x60000 W6 CTRL_CORE_PAD_MMC1_CLK mmc1_clk mmc1_clk
/* MMC1_DEFAULT */

Hi Terence,

there is a perl script that can convert PinMuxTool output to a format usable in mux_data.h. You can find instructions in Appendix B and C in this Application Note (it is for AM57xx, but also works on DRA7x and TDA2x):

please try it and let me know if you face any problems.

Regards,

Yordan

Hi Yordan,

Thank you very much.

According to your suggestion, we get padconf.txt & iodelay.txt. For TDA2PX device, it should modify dra76x_core_padconf_array in uboot/board/ti/dra7xx/mux_data.h. While, for TDA2HG, which pad_conf_entry & iodelay_cfg_entry we should apply the padconf.txt & iodelay.txt?

Hi Terence,

for TDA2HG you need to modify dra74x_core_padconf_array.

Hi Yordan,

Thank you very much.

Where can we get the EMIF configuration tools?

According the above pdf you gived us, we can not open that the chapter 5 said EMIF configuration tools. Also we can not open that the chapter 3.1 said how to step-by-step procedures for the EMIF configuration tool.

Thanks
