Linux/AM5716: eMMC not detected

Frantz,

I'm assuming this is based on SDK 4.x (kernel 4.9) since SDK 5.00 just came out today.  Is that correct?

Can you please share a snippet from your dts showing the mmc2 configuration?

Does your dts file include this file:

#include "dra72x-mmc-iodelay.dtsi"

Best regards,
Brad

Hi Brad,

Yes, I'm using SDK 4.x and I updated my git repository with the last version before SDK 5.00. Below, my u-boot env, new kernel log and after my DTS file.

Can you or a hardware person please check those buses?  Is there perhaps a power rail that isn't coming up as expected?  I'm wondering if that could also be related to your MMC issue, though that's not quite the type of error I would have expected.

               };

The first group corresponds to MMC1 (i.e. SD card interface) while the second group corresponds to MMC2 (eMMC).  Given that SD and MMC have slightly different modes of operation, that makes sense that they have different sets of pin mux settings.

Have you made changes to the default print levels or anything?  On the one hand, the messages about missing sdr25, sdr50, etc. make sense since those are not modes for eMMC.  On the other hand, I don't see those messages on my own AM571x IDK.

What do you have in your eMMC?  Has it already been partitioned and formatted?

There's nothing in my emmc and it hasn't been formatted either.
What information can I give you? How can I help you debug?
How can I format my emmc from u-boot?

Here's a script I adjusted to format the eMMC on the AM571x IDK.  It was derived from this script that also copied from SD card to eMMC, though for now I'm just focused on getting partitions created...

Please try running it from your target and it will format eMMC similar to a bootable SD card, i.e. bootable FAT partition plus ext4 partition.

If you run fdisk -l /dev/mmcblk1 before and after you should see the difference.

Also, my board takes about 60 seconds to launch the kernel, would you know why?

Please start a new thread for this one.

I'm sorry but I don't have a SD card (no connector) on my board, only the emmc is available. That's why I disabled the sd card in the DTS file (See AM57xx-idk-common.dtsi in a upper post). That's a custum board based on AM571x-idk. Do you have another way to do the same thing?

What are your sysboot settings? Do you have any peripheral (UART, USB) in your boot order?

When I boot my board, I see messages like this:

[ 3.783429] mmc0: new ultra high speed SDR104 SDHC card at address 59b4
[ 3.795188] mmc1: new DDR MMC card at address 0001

It seems like your board is not detecting that there is an eMMC device present.  Can you please verify that all the pullup resistors on the MMC2 interface have been populated during assembly, and also verify that the power rail is active for the pull-up (i.e. the 3.3V rail needs to be on).

It looks like you have the necessary pin muxing in place based on the dtb you posted, though if we're not getting anywhere we will probably want to use devmem2 to inspect those registers and confirm the expected pin muxing is present.

Thanks for the note.  That seems to explain these errors you saw in your kernel logs:

[ 62.718479] SMPS9: supplied by VMAIN
[ 62.718808] smps9: Bringing 0uV into 3300000-3300000uV

[ 62.720004] palmas-pmic: probe of 48070000.i2c:tps659038@58:tps659038_pmic failed with error -22

The only thing that's not clear to me is why you see those messages, but I don't see them on the AM571x IDK.

Indeed, we have the regulator TPS6590378 on our board. However SMPS9 is not connected to anything, but when I made this change in the device tree, the eMMC worked and was seen by the kernel.

Here's a snippet from am57xx-beagle-x15-common.dtsi:

smps6_reg: smps6 {

/* VDD_CORE */
regulator-name = "smps6";
regulator-min-microvolt = <850000>;
regulator-max-microvolt = <1150000>;
regulator-always-on;
regulator-boot-on;
};

/* SMPS7 unused */

smps8_reg: smps8 {
/* VDD_1V8 */
regulator-name = "smps8";
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <1800000>;
regulator-always-on;
regulator-boot-on;
};

/* SMPS9 unused */

ldo1_reg: ldo1 {
/* VDD_SD / VDDSHV8 */
regulator-name = "ldo1";
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <3300000>;
regulator-boot-on;
regulator-always-on;
};

The EVM uses TPS6590378 with SMPS9 unconnected.  See above how it's left completely out of the dts (and same for SMPS7).

So fundamentally I think you might have a mismatch between your power architecture and your dts.  It sounds like your power architecture derives from the EVM, but your dts is defining the architecture like the IDK.  So you should delete the nodes related to SMPS7 and SMPS9 if they are unconnected on your board.  Also, I would strongly recommend double checking SMPS8.  You probably need to define it similar to the snippet above if you're expecting SMPS8 to output 1.8V.
