Hi,

I try to set omap mmc hs mode in 192M , it's probability of failure. The error is:

"omap_hsmmc 480b4000.mmc: ADMA err: ST_TFR, desc at 0xfd841008 follows the erroneous one"

my emmc is Micron, my current config is:

&mmc2 {
/* SW5-3 in ON position */
status = "okay";

  vmmc-supply = <&evm_3v3_sw>;
  bus-width = <8>;
  ti,non-removable;
  max-frequency = <192000000>;

  pinctrl-names = "default", "hs", "ddr_1_8v", "hs200_1_8v";
  pinctrl-0 = <&mmc2_pins_default>;
  pinctrl-1 = <&mmc2_pins_hs>;
  pinctrl-2 = <&mmc2_pins_ddr_1_8v>;
  pinctrl-3 = <&mmc2_pins_hs200_1_8v &mmc2_iodelay_hs200_1_8v_conf>;
};

mmc2_iodelay_hs200_1_8v_conf: mmc2_iodelay_hs200_1_8v_conf {
pinctrl-single,pins = <
0x194 (A_DELAY(285) | G_DELAY(0)) /* CFG_GPMC_A19_OUT */
  0x1AC (A_DELAY(189) | G_DELAY(0)) /* CFG_GPMC_A20_OUT */
  0x1B8 (A_DELAY(0) | G_DELAY(120)) /* CFG_GPMC_A21_OUT */
  0x1C4 (A_DELAY(0) | G_DELAY(70)) /* CFG_GPMC_A22_OUT */
  0x1D0 (A_DELAY(730) | G_DELAY(360)) /* CFG_GPMC_A23_OUT */
  0x1DC (A_DELAY(0) | G_DELAY(0)) /* CFG_GPMC_A24_OUT */
  0x1E8 (A_DELAY(0) | G_DELAY(0)) /* CFG_GPMC_A25_OUT */
  0x1F4 (A_DELAY(70) | G_DELAY(0)) /* CFG_GPMC_A26_OUT */
  0x200 (A_DELAY(0) | G_DELAY(0)) /* CFG_GPMC_A27_OUT */
  0x368 (A_DELAY(0) | G_DELAY(120)) /* CFG_GPMC_CS1_OUT */
  0x190 (A_DELAY(0) | G_DELAY(0)) /* CFG_GPMC_A19_OEN */
  0x1A8 (A_DELAY(231) | G_DELAY(0)) /* CFG_GPMC_A20_OEN */
  0x1B4 (A_DELAY(39) | G_DELAY(0)) /* CFG_GPMC_A21_OEN */
  0x1C0 (A_DELAY(91) | G_DELAY(0)) /* CFG_GPMC_A22_OEN */
  0x1D8 (A_DELAY(176) | G_DELAY(0)) /* CFG_GPMC_A24_OEN */
  0x1E4 (A_DELAY(0) | G_DELAY(0)) /* CFG_GPMC_A25_OEN */
  0x1F0 (A_DELAY(101) | G_DELAY(0)) /* CFG_GPMC_A26_OEN */
  0x1FC (A_DELAY(0) | G_DELAY(0)) /* CFG_GPMC_A27_OEN */
  0x364 (A_DELAY(360) | G_DELAY(0)) /* CFG_GPMC_CS1_OEN */
>;
};

When I set max-frequency less than 192000000,the probability of recurrence is reduced.，I don’t know how to slove the trouble.

thank you!

Hi,

I have forwarded your question to MMC experts.

Can you just tell which version is your SDK?

Yordan

We are based on the following branches.

address: git://git.omapzoom.org branch: kernel/omap SHA: c22b04c9c6c436fbc14f6c812643a7cf64ebcd18

processor-sdk-linux-automotive-3.03.00.03 7e6588b179498e3a8e12011a4ee74513e26a833e

1) git.omapzoom.org/ is the commit sha for 3.14 kernel same as git.omapzoom.org/ ( This is not accurate for what you are trying to enable)

2) processor-sdk-linux-automotive-3.03.00.03 7e6588b179498e3a8e12011a4ee74513e26a833e is the correct kernel tag.
Also ensure you pick the uboot tag associated with this release.

3) DRA72x/ J6 Eco EVM (Rev C) is the supported device . Assuming you have the supported EVM.

4) Refer on configuring HS200/192Mhz : git.omapzoom.org/

HI,
There's a silicon erratum - i929 that could also cause the error that you are seeing.
Can you move to Processor-sdk-Linux-automotive-3.04 release and test?

HI,
A workaround for the erratum I mentioned above has been added to MMC driver in 3.04 release. So, give it a try with 3.04 release.

Hi,
I had merge the 3.04 release(742f84423d8eb464e85520b16c9424b4498f5665), the question is fixed;
But there is another problem. the MMC Initialition would faid sometion. The probability of 10% ;

Hi,

This looks like a timeout. You need to enable debug logs so that we can analyse further.

Hi:

As shown below when i enable debug and the timeout had happened in enable the HPI;

/*

* Enable HPI feature (if supported)

*/

if (card->ext_csd.hpi) {

err = mmc_switch(card, EXT_CSD_CMD_SET_NORMAL,

EXT_CSD_HPI_MGMT, 1,

card->ext_csd.generic_cmd6_time);

if (err && err != -EBADMSG) {

printk(KERN_ERR "mmc %d %d\n", __LINE__, card->ext_csd.rev);

goto free_card;

}

Hi,
Look at the following error:

mmc0:

You might be using an old device tree file. Please refer to "pbias_regulator" node in arch/arm/boot/dts/dra7.dtsi
73047.14> [ 0.949207] pbias_mmc_omap5: unsupportable voltage range: 3300000-3000000uV
73047.14> [ 0.956211] omap_hsmmc 4809c000.mmc: pbias set voltage failed

mmc1:
All the commands have timed out, the card does not seem to be responding at all. Either the voltage regulator is not correct or voltage is not applied correctly.

Regards,
RK
