Other Parts Discussed in Thread: AM3352

Hi,

we are using AM3352 processor and SDK-08 we are using custom board but -- Sitara Stater kit is the reference for mmc -- all PIN connections are same.

mmc1- dts file configuration:

mmc1_pins_default: pinmux_mmc1_pins {
pinctrl-single,pins = <
0x0F0 (PIN_INPUT_PULLUP | MUX_MODE0) /* mmc0_dat3.mmc0_dat3 */
0x0F4 (PIN_INPUT_PULLUP | MUX_MODE0) /* mmc0_dat2.mmc0_dat2 */
0x0F8 (PIN_INPUT_PULLUP | MUX_MODE0) /* mmc0_dat1.mmc0_dat1 */
0x0FC (PIN_INPUT_PULLUP | MUX_MODE0) /* mmc0_dat0.mmc0_dat0 */
0x100 (PIN_INPUT_PULLUP | MUX_MODE0) /* mmc0_clk.mmc0_clk */
0x104 (PIN_INPUT_PULLUP | MUX_MODE0) /* mmc0_cmd.mmc0_cmd */ // for this pin the below error is occurring
0x1A0 (PIN_INPUT_PULLUP | MUX_MODE7) /* mcasp0_aclkr.gpio3_18 */ --// i dont know why this pin is using -- which is not related -- without this kernel is not // loading completely it is stoping before wakeup of other CPUs
0x160 (PIN_INPUT | MUX_MODE7) /* spi0_cs1.gpio0_6 */
>;
};

Hi Viswanath,

Which DTS are you using, i guess am335x-evmsk.dts, right?

If so, have you modified the file or have you included some common dtsi, where that pin mmc0_cmd.mmc0_cmd is duplicated? Can you share the modifications?

Best Regards,
Yordan

Can you try changing:

mmc1_pins_default: pinmux_mmc1_pins

mmc1_pins_default: pinmux_mmc1_pins_default

Best Regards,

Yordan

Hi Yordan,

YES I done the update of adding mmc1_pins_default: pinmux_mmc1_pins_default :
this is the log:
[ 6.466020] pinctrl-single 44e10800.pinmux: pin 44e109a0.0 already requested by 44e10800.pinmux; cannot claim for 48060000.mmc

ofcourse linux is booting earlier and now also. But we are having doubt -- this may hit in the future.

Hi Vishwanath,

What does the devmem2 0x44e109a0 command return?

Does it apply the settings from mmc pinmux or something else?

Best Regards,
Yordan
