It works, now :)
Great!
tmio_mmc_init_ocr()
fails (silently!). And with this the whole RCar3 SDHI, without any error
message.
I'll check next week about an error message there.
Many thanks for your help!
You're welcome. If you want, you can even test SDR104 by applying this
patch:
[RFT] arm64: dts: renesas: salvator-common: enable SDR104 for SD cards
It works fine here for SD cards. My SDIO card makes problems, but that
might be the line length is just too long. We are currently evaluating
that. So, testing SDR104 on various boards would be very helpful!
I'm not an expert on this, does SDR104 need 1.8V?
To my understanding, sd-uhs-sdr50 is the max speed for 3.3V?
I ask because on my custom board the hardware guys gave us 3.3V, only,
for the SD slot :(
P.S.: Will try to send the pin mux patch tomorrow.
Thanks, I'll have a look at it next week then, too.
Patch sent.
Best regards
Dirk
