PROCESSOR-SDK-AM437X: MMC1 configuration in U-boot

Rio Chan

Part Number: PROCESSOR-SDK-AM437X
Other Parts Discussed in Thread: AM4372

Hi Champs.

If booting the MMC2 on AM437, do we need to modify the DTS for uboot?

If yes, how to do that?

Besides, please review my attached DTS for kernel.

Thanks.

Sorry, the previous attached is the uboot DTS.

please help to review.

Hi Rio,

if you want to use a different MMC I/F you need to update the board-specific pinmux file at board/ti/am43xx/mux.c.

When you build for AM43xx using the am43xx_evm_defconfig the pin mux driver (CONFIG_PINCTRL_SINGLE) is not used, hence the DTS definitions related to pin mux will not be used in the context of U-Boot. Please check this board file (or a similar one, in case of a custom board), and make adjustments there accordingly, with the help of our pinmux tool.

Regards, Andreas

Hi Andrea:

Thanks.

I have 1 important question.

The Pinmux tool generated the DTSI as below section.

sd_mmc_pins_default: sd_mmc_pins_default {
pinctrl-single,pins = <
AM4372_IOPAD(0x900, PIN_INPUT_PULLUP | MUX_MODE0) /* (D1) mmc0_clk.mmc0_clk */
AM4372_IOPAD(0x904, PIN_INPUT_PULLDOWN | MUX_MODE0) /* (D2) mmc0_cmd.mmc0_cmd */
AM4372_IOPAD(0x8fc, PIN_INPUT_PULLUP | MUX_MODE0) /* (C1) mmc0_dat0.mmc0_dat0 */
AM4372_IOPAD(0x8f8, PIN_INPUT_PULLUP | MUX_MODE0) /* (C2) mmc0_dat1.mmc0_dat1 */
AM4372_IOPAD(0x8f4, PIN_INPUT_PULLUP | MUX_MODE0) /* (B2) mmc0_dat2.mmc0_dat2 */
AM4372_IOPAD(0x8f0, PIN_INPUT_PULLUP | MUX_MODE0) /* (B1) mmc0_dat3.mmc0_dat3 */
AM4372_IOPAD(0x960, PIN_INPUT_PULLUP | MUX_MODE5) /* (R25) spi0_cs1.mmc0_sdcd */
>;
};

And the SDK uboot DTSI is not the same format as the Pnmux tool generated.

So, the value I need to assign needs to be minus 0x800 for each pin?

That mean 0x900 in the above, it needs to be set as 0x100 in the below?

sdmmc_pins: pinmux_sdmmc_pins {

pinctrl-single,pins = <

0x100 (PIN_INPUT | MUX_MODE1) /* mmc0_clk.mmc0_clk , Rio: LNC: D1 */
0x104 (PIN_INPUT | MUX_MODE1) /* mmc0_cmd.mmc0_cmd , Rio: LNC: D2 */
0x0fc (PIN_INPUT | MUX_MODE1) /* mmc0_dat0.mmc0_dat0, Rio: LNC: C1 */
0x0f8 (PIN_INPUT | MUX_MODE1) /* mmc0_dat1.mmc0_dat1, Rio: LNC: C2 */
0x0f4 (PIN_INPUT | MUX_MODE2) /* mmc0_dat2.mmc0_dat2, Rio: LNC: B2 */
0x0f0 (PIN_INPUT | MUX_MODE2) /* mmc0_dat3.mmc0_dat3, Rio: LNC: B1 */
0x160 (PIN_INPUT | MUX_MODE4) /* spi0_cs1.mmc0_sdcd , Rio: LNC: R25 */
>;
};

my point is: the pinmux generated value needs to be -0x800 while adapting into the uboot DTSI?

please review my code section as above and comment.

THanks.

Hi Rio,

Rio Chan said:

See how the pinmux-generated output uses a macro to populate the value. The macro will take care of the "-0x800".

a0797059@jiji:~/git/u-boot (ti-u-boot-2020.01)
$ git grep AM4372_IOPAD include/dt-bindings
include/dt-bindings/pinctrl/am43xx.h:#define AM4372_IOPAD(pa, val)      (((pa) & 0xffff) - 0x0800) (val)

This being said the pinmux-generated section should just be copy & paste into the DTS file. But if you are still trying to get U-Boot to work you need to update the mux.c file I pointed to earlier. But I guess you just wanted to understand how to translate the values. You could also generate pinmux data for MMC0, and compare to what is already in mux.c, so you can see exactly how those relate.

Regards, Andreas

Hi Andreas:

How to use this tool? ==>git grep AM4372_IOPAD include/dt-bindings

Any document / example to guide me how to do that?

THanks.

'git grep' is really a Git version of the ubiquitous 'grep' tool in the *nix world. It helps limiting the search scope to the files actually checked into the git repository, and by default operates recursively (unless you give it a specific file or path like I did). So it is very very fast and convenient as compared to using the regular 'grep -r' for example. Plus it has a ton of Git-specific extra features. Usually I use it to browse/analyze source code quickly from the command line. Often I also add a '-C 20' parameter or so in there to see the surrounding +/-20 lines of source code of a search match. And from there I tweak my search mask or seach folder over a few iteration. Helps me personally to find stuff very quickly, but it's just my way of doing it (different folks have different methods). Anyways you can find more info here... https://git-scm.com/docs/git-grep
