SD-Card isn't working...

[jojo-gfx]

Has anyone tried out the actual version with SD-Reader?
Have no frequency output on clock signal. It's standing only on 3,2V (have no scope and could be too short impulse because errors) and so also ESP32 don't start really.
If I set SD-card off all other is running normal.

Have seen now on serial console, the ESP is resetting permanently because an error!?

Would be nice the project would be developed also in future, because I don't know such a nice thing with AV output. :(

Ok, this was without an SD-Card.
With SD-Card is the error so:
-> Rebooting...
10:36:55.348 -> E (376) sdmmc_sd: sdmmc_init_spi_crc: sdmmc_send_cmd_crc_on_off returned 0x106

Ok, for all with such problems: Look on the write-protection! It has to be unlocked!

Now the serial output looks better, but still ni Output on AV and this:

... and clock still without frequency.

p.s.
I'm using several small SD-Cards for testing, with small partitions (down to 50MB) and FAT16 with short names, but how you can see...

Ok, after format a same card per CMD format X: /FS:FAT /Q the following is coming up in console:

11:15:54.991 ->
11:15:54.991 -> rst:0x10 (RTCWDT_RTC_RESET),boot:0x33 (SPI_FAST_FLASH_BOOT)
11:15:55.065 -> invalid header: 0xffffffff
11:15:55.110 -> invalid header: 0xffffffff
11:15:55.142 -> invalid header: 0xffffffff
11:15:55.188 -> invalid header: 0xffffffff
11:15:55.234 -> invalid header: 0xffffffff
11:15:55.266 -> invalid header: 0xffffffff
11:15:55.312 -> invalid header: 0xffffffff
11:15:55.357 -> ets Jul 29 2019 12:21:46
11:15:55.357 ->

Seems, the card is read, but the format seems to be wrong.

I have to find now a Win XP or so to format it right.
Seems the implementation of filesystem is really unstable. :(

Hi everyone, first of all, thank you for this great project. One question, has anyone managed to emulate with an SD card? I've tried a lot of things and there's no way, the micro keeps rebooting. Regards.
