Original question:

TDA4VE-Q1: TDA4VE EMMC initialization problem

TDA4VE-Q1: eMMC boot fail when kernel using HS200 mode

Liu Hawayi
Prodigy 40 points
Part Number: TDA4VE-Q1
Other Parts Discussed in Thread: TDA4VM

Hi Experts:

We are using an eMMC (part no:KLM8G1GEUF-B04Q),which can be boot normally on TDA4VM platform by using HS200 mode.

But it boot fail on TDA4VE platform when using the same mode.Our SDK version is "9.1.0.6", the frequency of eMMC on uboot is 52MHz.

BTW, The eMMC can boot normally when setting otap-del-sel-mmc-hs mode. Our dts setting as below:

main_sdhci0: mmc@4f80000 {
compatible = "ti,j721e-sdhci-8bit";
reg = <0x00 0x04f80000 0x00 0x1000>,
<0x00 0x04f88000 0x00 0x400>;
interrupts = <GIC_SPI 3 IRQ_TYPE_LEVEL_HIGH>;
power-domains = <&k3_pds 98 TI_SCI_PD_EXCLUSIVE>;
clocks = <&k3_clks 98 7>, <&k3_clks 98 1>;
clock-names = "clk_ahb", "clk_xin";
assigned-clocks = <&k3_clks 98 1>;
assigned-clock-parents = <&k3_clks 98 2>;
bus-width = <8>;
ti,otap-del-sel-legacy = <0x0>;
ti,otap-del-sel-mmc-hs = <0x0>;
//ti,otap-del-sel-ddr52 = <0x6>;
ti,otap-del-sel-hs200 = <0x8>;
//ti,otap-del-sel-hs400 = <0x5>;
ti,itap-del-sel-legacy = <0x10>;
ti,itap-del-sel-mmc-hs = <0xa>;
ti,strobe-sel = <0x77>;
ti,clkbuf-sel = <0x7>;
ti,trm-icp = <0x8>;
mmc-ddr-1_8v;
mmc-hs200-1_8v;
//mmc-hs400-1_8v;
dma-coherent;
};

when I try add node "sdhci-caps-mask = <0x80000000 0x0>;" on that dts, it fail as before, Please refer the log  and help us to fix the issue, thanks!

    HI Hawayi

    quick question why we are not using HS400 speed mode here ?

    Regards

    Hi Diwakar:

    Because we used HS200 speed mode on TDA4VM for mass production for several years, and HS200 is enough for us.secondly, if I set HS400 speed mode as default, it fail to boot again.

    1、dts setting:

    main_sdhci0: mmc@4f80000 {
    compatible = "ti,j721e-sdhci-8bit";
    reg = <0x00 0x04f80000 0x00 0x1000>,
    <0x00 0x04f88000 0x00 0x400>;
    interrupts = <GIC_SPI 3 IRQ_TYPE_LEVEL_HIGH>;
    power-domains = <&k3_pds 98 TI_SCI_PD_EXCLUSIVE>;
    clocks = <&k3_clks 98 7>, <&k3_clks 98 1>;
    clock-names = "clk_ahb", "clk_xin";
    assigned-clocks = <&k3_clks 98 1>;
    assigned-clock-parents = <&k3_clks 98 2>;
    bus-width = <8>;
    ti,otap-del-sel-legacy = <0x0>;
    ti,otap-del-sel-mmc-hs = <0x0>;
    ti,otap-del-sel-ddr52 = <0x6>;
    ti,otap-del-sel-hs200 = <0x8>;
    ti,otap-del-sel-hs400 = <0x5>;
    ti,itap-del-sel-legacy = <0x10>;
    ti,itap-del-sel-mmc-hs = <0xa>;
    ti,strobe-sel = <0x77>;
    ti,clkbuf-sel = <0x7>;
    ti,trm-icp = <0x8>;
    mmc-ddr-1_8v;
    mmc-hs200-1_8v;
    mmc-hs400-1_8v;
    dma-coherent;
    };

    Hi Liu 

    Can you try running HS200 in uboot ?

    Just to do deeper analysis whether UBOOT is working fine or not.

    Regards

    Hi Diwakar:

    We try running HS200 in uboot, it's working fine. It's same configuration about mmc0, but working bad in kernel.

    Best Regards

    Can you apply the below patch and see if it works now.

    HI Hawayi 

    Why it is commented HS400 and HS200 work at 1.8 v?

    Liu Hawayi said:
    mmc-ddr-1_8v;
    //mmc-hs200-1_8v;
    //mmc-hs400-1_8v;

    Also when you are trying running the HS200 in uboot can you run the command in UBOOT and share the info.

    • mmc dev 0 
    • mmc info

    HI Hawayi

    Can you share the below details as well.

    • What is the boot flow you are using ?
    • Help share the full boot logs after making the changes in the dtsi.
    • Help share the dtb (not disi) which you used in the linux and u-boot.dtb used at uboot stage.

    Regards
    Diwakar

    Hi Hawayi

    Seems the EMMC is not responding to the command in linux.

    I would suggest you to add the OTAP/ITAP values for all modes as per the dtsi in the sdk.

    bus-width = <8>;
    ti,otap-del-sel-legacy = <0x0>;
    ti,otap-del-sel-mmc-hs = <0x0>;
    ti,otap-del-sel-ddr52 = <0x6>;
    ti,otap-del-sel-hs200 = <0x8>;
    ti,otap-del-sel-hs400 = <0x5>;
    ti,itap-del-sel-legacy = <0x10>;
    ti,itap-del-sel-mmc-hs = <0xa>;
    ti,strobe-sel = <0x77>;
    ti,clkbuf-sel = <0x7>;
    ti,trm-icp = <0x8>;
    mmc-ddr-1_8v;
    mmc-hs200-1_8v;
    mmc-hs400-1_8v;
    dma-coherent;

    can you enable more logs (particularly from sdhci.c )in the linux  to get more details about that failure.

    Hi Diwakar:

    I use the following configuration and apply the patch that you provide, then it's ok, the kernel print that "mmc0: new HS200 MMC card at address 0001".

    But I am not sure whether there is any risky about applying the patch? why the patch is not applied on original sdk?

    main_sdhci0: mmc@4f80000 {
    compatible = "ti,j721e-sdhci-8bit";
    reg = <0x00 0x04f80000 0x00 0x1000>,
    <0x00 0x04f88000 0x00 0x400>;
    interrupts = <GIC_SPI 3 IRQ_TYPE_LEVEL_HIGH>;
    power-domains = <&k3_pds 98 TI_SCI_PD_EXCLUSIVE>;
    clocks = <&k3_clks 98 7>, <&k3_clks 98 1>;
    clock-names = "clk_ahb", "clk_xin";
    assigned-clocks = <&k3_clks 98 1>;
    assigned-clock-parents = <&k3_clks 98 2>;
    bus-width = <8>;
    ti,otap-del-sel-legacy = <0x0>;
    ti,otap-del-sel-mmc-hs = <0x0>;
    ti,otap-del-sel-ddr52 = <0x6>;
    ti,otap-del-sel-hs200 = <0x8>;
    //ti,otap-del-sel-hs400 = <0x5>;
    ti,itap-del-sel-legacy = <0x10>;
    ti,itap-del-sel-mmc-hs = <0xa>;
    ti,strobe-sel = <0x77>;
    ti,clkbuf-sel = <0x7>;
    ti,trm-icp = <0x8>;
    mmc-ddr-1_8v;
    mmc-hs200-1_8v;
    //mmc-hs400-1_8v;
    dma-coherent;
    };

    Hi Hawayi

    The is no risk in applying the patch 

    Our emmc controller in-compliance with JEDEC’s MMC Specification Version 5.1 so any emmc with <= emmc 5.1 will work 

    Samsung eMMC parts are JEDEC 5.1 compatible, and thus should be supported by our device out of the box.

    However, we have seen Samsung eMMCs behave less robustly than the Micron parts we use internally, primarily when switching to 1.8V signaling at boot (and at the same time switching from issuing commands on the falling edge of the clock (full-cycle timing) to instead issuing on the rising edge (half-cycle timing). A software update in which we ensure that full-cycle timing is maintained all the way through the transitional period should be provided in order to account for the reduced margin on Samsung parts

    Regards

    Hi Diwakar:

    Ok, I know it. Thanks for your help.
