I’ve just read through properly - ignore me, I got totally the wrong end of the stick.
Well how about booting from a hard disk? I can test that here although I’ve got some catching up to do in terms of process and patches etc
(I can’t vouch for everybody’s usage pattern but the SD is just a fancy boot rom to me now)
still nobody has an idea?
aplied patch from http://lists.infradead.org/pipermail/linux-mediatek/2017-October/010827.html, changed mmc1 to mt2701 and the clock, nothing changes
but i’m not sure if mmc1 is the problem…

in bootlog it seems mmc0=11240000.mmc=mmc from dts, can you confirm that? in shematicts sdxc should be 4-bit-data (MDSC_DAT0 - MSDC_DAT3)
@Ryder.Lee @linkerosa do you see your SD-Card with kernel 4.14?? which Cards do you use?
Could you provide boot log to me?
Can i activate a “debug-mode”? in current boot-log there are only above lines with mmc…
here the normal boot.log: 14.4.boot.log (48,8 KB)
14.4.patch (7,0 KB)
forum is extremely slow the last days…
@ryder.lee have you found something in log or can you reproduce the problem?
maybe i can put some debug-messages in mtk-sd.c or enable the existing somehow, but currently i don’t know how the probing is working (which functions are called in which order, which function is the entrypoint). ~2000 line are much for my limited c+±knowledge ;(
as far as i know one of the main functions is “static int msdc_drv_probe(…)”, which seems similar except of new function msdc_of_property_parse which does the of_property-calls which are done in 4.4.70 with debug-messages “dev_dbg(…)”
i’ve found some strange definitions in include/linux/mmc/host.h: 4.4.70:
#define MMC_CAP_ERASE (1 << 10) /* Allow erase/trim commands */
#define MMC_CAP_1_8V_DDR (1 << 11) /* can support */
/* DDR mode at 1.8V */
#define MMC_CAP_1_2V_DDR (1 << 12) /* can support */
/* DDR mode at 1.2V */
#define MMC_CAP_POWER_OFF_CARD (1 << 13) /* Can power off after boot */
#define MMC_CAP_BUS_WIDTH_TEST (1 << 14) /* CMD14/CMD19 bus width ok */
#define MMC_CAP_UHS_SDR12 (1 << 15) /* Host supports UHS SDR12 mode */
#define MMC_CAP_UHS_SDR25 (1 << 16) /* Host supports UHS SDR25 mode */
#define MMC_CAP_UHS_SDR50 (1 << 17) /* Host supports UHS SDR50 mode */
#define MMC_CAP_UHS_SDR104 (1 << 18) /* Host supports UHS SDR104 mode */
#define MMC_CAP_UHS_DDR50 (1 << 19) /* Host supports UHS DDR50 mode */
#define MMC_CAP_RUNTIME_RESUME (1 << 20) /* Resume at runtime_resume. */
4.14:
#define MMC_CAP_ERASE (1 << 10) /* Allow erase/trim commands */
#define MMC_CAP_3_3V_DDR (1 << 11) /* Host supports eMMC DDR 3.3V */
#define MMC_CAP_1_8V_DDR (1 << 12) /* Host supports eMMC DDR 1.8V */
#define MMC_CAP_1_2V_DDR (1 << 13) /* Host supports eMMC DDR 1.2V */
#define MMC_CAP_POWER_OFF_CARD (1 << 14) /* Can power off after boot */
#define MMC_CAP_BUS_WIDTH_TEST (1 << 15) /* CMD14/CMD19 bus width ok */
#define MMC_CAP_UHS_SDR12 (1 << 16) /* Host supports UHS SDR12 mode */
#define MMC_CAP_UHS_SDR25 (1 << 17) /* Host supports UHS SDR25 mode */
#define MMC_CAP_UHS_SDR50 (1 << 18) /* Host supports UHS SDR50 mode */
#define MMC_CAP_UHS_SDR104 (1 << 19) /* Host supports UHS SDR104 mode */
#define MMC_CAP_UHS_DDR50 (1 << 20) /* Host supports UHS DDR50 mode */
as you can see MMC_CAP_ERASE is same, after that in 4.14 MMC_CAP_3_3V_DDR is inserted and the other constants are now 1 higher bit…maybe this is the Problem (seems it’s only for kernel-internal option-storing)?
trying to include code from 4.4.70, 1st step (not working so far, but maybe a help) 14.4.sd.diff (12,5 KB)

I don’t understand the event-messages but buswidth seems strange…i think it must be 4,or am i wrong? also that looks not good:

#./include/uapi/asm-generic/errno.h:93:#define ETIMEDOUT 110 /* Connection timed out */ ???

4.14 is missing event 100 for SD-Card (1124) like that in 4.4.70
11240000.mmc: msdc_irq: events=00000100
while greping for the constants i’ve found out that 4.4.70 has also files in drivers/misc/mediatek/mtk_sdio/… these are missing in 4.14, but it seems is not activated in 4.4.70-kernel (# CONFIG_MMC_MTK_SDIO is not set)
currently i don’t know how msdc_irq works and where the events are set…because MSDC_INTEN seems to be an offset for the events, they may be set by that lines:
kernel_4.14/linux/drivers/mmc/host/mtk-sd.c:550: flags = readl(host->base + MSDC_INTEN);
kernel_4.14/linux/drivers/mmc/host/mtk-sd.c:551: sdr_clr_bits(host->base + MSDC_INTEN, flags);

kernel_4.14/linux/drivers/mmc/host/mtk-sd.c:1212: writel(0, host->base + MSDC_INTEN);
i try to include “drivers/mmc/card” from 4.4.70
Could you give me your dts/dtsi and mtk-sd.c ?
Try the below node:
&mmc1 {
pinctrl-names = "default", "state_uhs";
pinctrl-0 = <&mmc1_pins_default>;
pinctrl-1 = <&mmc1_pins_uhs>;
status = "okay";
bus-width = <4>;
max-frequency = <50000000>;
cap-sd-highspeed;
cd-gpios = <&pio 261 0>;
vmmc-supply = <&mt6323_vmch_reg>;
vqmmc-supply = <&mt6323_vio18_reg>; --》vqmmc-supply = <&mt6323_vmc_reg>
};currently i reverted all changes and have original 4.14 final code. All changes (merging of mtk-sd.c and changes in dtsi are in my last post “14.4.patch11”)
You changed the regulator in last line?
Take the patches http://lists.infradead.org/pipermail/linux-mediatek/2017-October/010827.html and try to change the regulator in last line.

Could you provide 4.14 full debug log? Did you detect SD card with those change?
sd not working yet. How to make full debug-log?
CONFIG_DYNAMIC_DEBUG=y
To enable dev_dbg messages in a specific kernel file:
#define DEBUG
i have dynamic_debug enabled and #define DEBUG in mtk-sd.c…any other options (#define debug in another file)?
maybe debug-log is somewhere in Filesystem? i uploaded the bootlog from minicom…
try to add “ccflags-y :=-DDEBUG” in makefile or CONFIG_CMDLINE=“loglevel=8”
added the “ccflags-y :=-DDEBUG” to drivers/mmc/Makefile (main makefile is very big…where is the right section?) and the loglevel:
# cat /proc/cmdline
earlyprintk console=ttyS0,115200 vmalloc=496M debug=7 loglevel=8 no_console_suspend
but still no more messages for the SD-Card:

maybe the “wp-gpio”-messages are the Problem?

Hi, Frank
Good news, I should have solved the problems.
it is a polarity problem that pin for card detected should be used as LOW ACTIVE instead of HIGH ACTIVE. it worked for me. you can follow below steps to see whether it worked for you.
please apply all patches https://patchwork.ozlabs.org/cover/823758/ you should have done as your previous replied

};After reviewing more on the 4.4 driver, i found the mtk-sd.c in 4.4 doesn’t have get_cd callback but it does in upstream kernel and thus 4.4 always bypasses the sanity check if card is present and upstream we MUST assign the exact what the core is expected to.
in drivers/mmc/core/core.c will check if get_cd is available.
if (mmc_card_is_removable(host) && host->ops->get_cd &&
host->ops->get_cd(host) == 0) {
mmc_power_off(host);
mmc_release_host(host);
goto out;
}
