I also hit this issue. In my case both C6 GPIO_NUM_4 & 5 are low or in a strange "floating state" but I cannot toggle them high...

OWN board with QFN40: https://github.com/martinberlin/H-C6-ul ... st.1.0.pdf

Hello Hardware forum,
I've committed last week a bad mistake and selected a C6 QFN40 for a design forgetting that this version does not come with built in flash.
So in order to avoid changing it for the more expensive QFN32 (With 4 MB Flash) I decided to go a step forward and add for the first time ...

Try this example:

https://github.com/espressif/esp-idf/tree/8fc8f3f4799/examples/peripherals/usb/device/tusb_msc

It does create files.
But using Flash SPI I still could not copy a 48Kb image successfully.
Program source: https://github.com/vroland/epdiy/tree/s3_color_implementation/examples/v7 ...

Did anyone succeed sending a file "modem style" via USB?

I tried and failed miserably so far :geek: . Checked the RZ / SZ ZModem Linux programs:

https://github.com/coderfordev/rzsz/blob/master/rz.c

And it seems at least complicated. So I guess would have to restrain to use SDCard also.
Just ...

HI @ESP_igrr
And sorry for the very long delay! It's been ages I don't come back here.
The card was a SanDisk Ultra 32 GB

Quick question here:
Anyone knows how is possible to set the arduino using a ESP32S3 board with 16 MB octal SPI, switch the Data cache line size to: 64 bytes

It's easy to do in IDF: → Component config → ESP System Settings → Cache config

But still didn't managed to do it in Arduino IDE.

I like the idea from Herr Metzner!

@ESP_Piyush would be really nice to get the phone datetime somehow so you can sync an RTC on board.

I will be trying this input forms soon since I'm building a small UX to control a device consumption for my project Bistable-smart-switch

I know that is like 7 years ago at least.

Today I tried with ESP-IDF v5. and after checking the wiring 2 times, it does work correctly with an SPI SD card module and a 16 GB card:


I (316) example: Using SPI peripheral
I (316) example: Mounting filesystem
I (326) gpio: GPIO[10]| InputEn: 0 ...

Awesome!
I will use this.

Thanks a lot.

Dear developers,
Can someone point me to an smart way to keep a CMakeFiles compatible for those who want to build also a project in ESP-IDF v5. But of course keeping backwards compatibility to 4.4 at least. I searched for CMakeFiles and IDF_VERSION but didn't found anything related. Please forgive ...
