I'm facing the same issue, I created this ticket:
https://github.com/espressif/esp-idf/issues/15971

I managed to append an include file to sdkconfig.h but the problem is that the freeRTOS build can't "see" other paths and I'm getting difficult to #include <searchable files>

it would work with ...

Same question:

esp_err_t SPI_MASTER_ISR_ATTR spi_device_acquire_bus(spi_device_t *device, TickType_t wait)
{
..
SPI_CHECK(!spi_bus_device_is_polling(device), "Cannot acquire bus when a polling transaction is in progress.", ESP_ERR_INVALID_STATE);
...
esp_err_t ret = spi_bus_lock_acquire_start ...

On ESP32 with emulated USB-UART, what is the expected maximum transmission rate?
I believe form the side of the host OS driver, the baudrate setting has no effect as it should be limited by USB transmission with the device?

If I have a running ESP, which I have access to its own running partition, can I directly copy that running partition (eg: via esp_partition_read), send all the data to another ESP via OTA (eg: using some esp library) ?

There's nothing wrong with it.

Code: Select all

void app_main()
{
....
}

Is that app_main running the FreerRTOS or not?

Eg: tasks can't be suspended while using these functions.

On my case the happened when I suspend all the OS tasks, like a "critical section"

What happens if after an firmware update, I update another one without marking the current one as valid?

I had a similar issue, I found that OS must be running while to access this functions.
Eg: tasks can't be suspended while using these functions.

I'm using (latest everything) VSCode, IDF extention, on Linux(Mint),
I create a project using the wizard, it creates a container, I open the workspace in container: I can't have write access to the files.

How did you implemented?

Two years later, still not much info on internet about it..

I have a component
I'm using idf_component_register and then I use externalproject_add.
It all builds, link and runs ok until I start to include ESP32 IDF libraries
then I get errors such as
fatal error: freertos/FreeRTOS.h: No such file or directory

How do I build external components but still ...
