Re: esptool.py and using hex format files

If it is a correct hex format, write_flash will work using:
esptool.py --port /dev/ttyUSB1 write_flash --flash_mode dio --flash_size 4MB 0x0 ${CMAKE_BINARY_DIR}/22143V${CI_BUILD_TAG}R${CI_COMMIT_SHORT_SHA}.${FORMAT}

Issues with ESP-IDF v5.2 using async handlers

I am trying to set up the webserver to be able to receive a file from the web page and then be able to query the progress from the web page to the webserver. Before I was using the async feature addition in 5.2 I had been able to upload the file from v 5.0. I had been reading that I had to upgrade t...

ESP32 SPI Chip Select Not working.

I am trying to use the spi, and the chip select is not being held low while transmission in progress. It is bouncining, and not very predictable on how many times or when. Is there a way to drive the cs low, send and receive all the data and then drive the cs high? I have tried many different code s...

Re: Using GPIO 2 and GPIO 25 not being able to be controlled.

Thank you, The issue has been resolved. I was working with the esp32 WROOM single antennae on a proprietary board, and went to a esp32 WROOM dual antennae eval board to test the signals. Upon further investigation this is expected operation of the 2 boards. On the single antennae board, the gpio do ...

Re: Using GPIO 2 and GPIO 25 not being able to be controlled.

I can post snippets of the code: //The #defines are actually set up into typedefs to control other GPIOs, that are working, 2, and 25 are 2 that I found are not controlled through this code. #define GPIO GPIO_NUM_2 // or whatever gpio to test #define GPIO_MASK (1ULL << GPIO) gpio_config_t config = {...

Using GPIO 2 and GPIO 25 not being able to be controlled.

I have tested several different gpios with my code and able to drive them high or low. But when I set up GPIO 2 and GPIO 25 to test for driving, they remain low. Any help to get these 2 pins to work would be appreciated.

Thank you in advance

I have worked with the ESP-IDF in the past, and also used esp-at that I was able to use and build locally. Basically I am needing to be able to conf...

Also I am looking for instructions on creating my own fatfs for my project. These are the function calls in this order that...
