mhhhh, so with fifo-mode mmc info is working
<rperier>
and if I reduce clock-max-frequency to 400khz (like for enumaration) mmc part is also working, while it did not work previously
<rperier>
it seems that we have clocks issue, but I am not sure
<phh>
wzyy2: you've seen my messages about cec?

rperier: cool
<rperier>
mrjay: thanks for your idea about fifo-mode btw
<mrjay>
rperier: np
<mrjay>
rperier: rperier: i'm using mmind clk driver adopted for rk3066 uboot
<mrjay>
rperier: and i'm also seing issue with setting clk frequency
<mrjay>
rperier: but in my case i needed to set min freq to 50Mhz
<mrjay>
rperier: for sdmmc
<rperier>
I need to set min freq to 400khz here (enumerate requires to be at least at 400khz) and max freq to 12.5Mhz here (sd version 1.0). that's local hack for now

rperier: does usb phy works in rk3188 uboot? you can test it with: mmc info; ums 0 mmc 0;

mhhhh, it not so deterministic, even at 800khz I get random timeouts on cmd17

anyway, I would have an invalid filename or an error from the fatfs point of view and not a cmd timeout
<rperier>
I tested it anyway, same issue
<mrjay>
rperier: weird i don't get thoose
<rperier>
you mean, it's working for you ?
<mrjay>
yes
<mrjay>
but i'm using uboot for rk3066
<mrjay>
not 3188
<rperier>
yes but the IP block for SDIO is almost the same no ?
<mrjay>
yes
<mrjay>
sdmmc
<rperier>
well, a lot of other stuffs might differ :/
<mrjay>
maybe clk driver?
<rperier>
and you're using uboot mainline... ?
<rperier>
yes, perhaps
wzyy2 has joined #linux-rockchip
<mrjay>
mainline + my patches :) + mminds clk driver
<wzyy2>
phh, I saw it. So HDMI-CEC is work with your branch?
<wzyy2>
I'll try it when I have time.....
<wzyy2>
QAQ, closed by a customer in the small room for a month.
<phh>
wzyy2: as I mentioned, currently I only have a c201 for kernel development, and c201 doesn't have hdmi-cec, though I no longer have faults, and when I change the pinmuxing, the behaviour is different, so everything looks good
<wzyy2>
Ok, I can try it in my EVB-board.
<phh>
wzyy2: to test, check you have /dev/cec0; then you need v4l-utils, and do cec-ctl -o rk3288 --record; cec-ctl -S
<phh>
the last cec-ctl should show you the tree of devices connected to cec bus
<mrjay>
rperier: maybe you have faulty microsd card?
