I am using this (very recent) version of the esp-idf:

I have 10k pullup resistors on all the lines as indicated in the readme
I am using a sparkfun sdmmc breakout : https://www.sparkfun.com/products/12941
My SD card is a scandisk 8gb HC 1.
I have burned the fuse to boot with 3.3v flash voltage, and I am pulling GPIO2 LOW during a flash, using a jumper, then disconnecting that jumper when flashing begins.
I have added the line

Others have reported using 4-line mode successfully, but I cannot figure out what the issue is here.
My only guess is the line

Code: Select all

GPIO[13]| InputEn: 0| OutputEn: 1| OpenDrain: 0| Pullup: 0| Pulldown: 0| Intr:0
indicates that something is changing the setting for GPIO13 and perhaps that is interfering.

0x109 is CRC error. This means that the communication is somewhat working, but not quite. This is usually related to voltage levels, noise, or long wiring. Suggested debugging approach is to use an oscilloscope to capture signals on D0-D3 lines, compare the voltage levels, see if the waveforms look reasonable w.r.t. the clock line.

I should add that I am using a new esp32 devkitc v4 wroom module, an official one through Mouser.
The example code explicitly sets GPIO13 pullup, but, the line I mentioned in the monitor output indicates that the pullup is not engaged. This commit of the IDF seems related to JTAG programming, and 13 is indeed a JTAG pin ... perhaps I'm making connections where there are none.
I will look with an oscilloscope today and report back thank you.

also please note, I edited my initial post to show verbose output (it wasn't before), if that causes confusion I apologize, I will add comments rather then editing next time.

I have scoped the outputs and they all appear as expected.
What would be the next step to debug this?

DevKitC does not have an on-board SD card slot... Can you describe how you are connecting the SD card to DevKitC?
It might also be worth checking voltage on GPIO12, as it is pulled down on DevKitC, but needs to be pulled up for SD card operation.

I am connecting the SD Breakout using shortest possible wires, and a bread board.
The voltage on GPIO12 behaves the same as all the other data lines when looking at the scope, except immediately after reset it is pulled down by about 1V (steady at about 2V) for a few ms.

As per the example readme I burned the fuses using

Code: Select all

components/esptool_py/esptool/espefuse.py set_flash_voltage 3.3V
The identical setup works very well with 1-line mode, even with

Code: Select all

host.max_freq_khz = SDMMC_FREQ_HIGHSPEED;
or even

Code: Select all

host.max_freq_khz = SDMMC_FREQ_52M;
When you say GPIO12 is pulled-down on devkitc, do you mean with an external pull-down resistor? I do not see this indicated in the schematic.

based on another thread I found on this forum, I tried removing both the pullup and sdcard connection from GPIO12 during reset, leaving GPIO12 completely unattached to any external circuitry, and keeping the pullup on the sdcard pin D2. I inserted a long pause into the code before sd card init process, and re-attaching the circuit to GPIO12 during this pause.

This actually works, but I am confused what this indicates, obviously I need a work-around for this.

can anyone help me find a solution that will allow me to leave my circuit attached? I have no clue what is going on.

thank you so much for all the help.

correction.
The above procedure worked simply because I was placing my hand on the SD CARD metal enclosure during the process. Its success has nothing to do with attaching and re-attaching the wires, with the normal circuit, and a finger on the SDCARD enclosure, everything works perfectly, so, it does indeed indicate to me that it is a signal integrity issue. I will debug further and report back.

Happy to report that after transferring my circuit from breadboard to a protoboard, the sd_card example now works in 4-line mode. I am getting about double the read speed with small random sector reads of 512 bytes, compared to 1-line mode.
I still occasionally get an error code 109, but i expect this to not occur once the circuit is on a proper pcb, with shorter lines.
