USB stack will not reinitialize after deinit. (IDFGH-14332) #15122
Description
Answers checklist.
- I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
- I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
- I have searched the issue tracker for a similar issue and not found a similar issue.
IDF version.
5.1.2
Espressif SoC revision.
esp32-s3
Operating System used.
macOS
How did you build your project?
Command line with idf.py
If you are using Windows, please specify command line type.
None
Development Kit.
custom
Power Supply used.
External 3.3V
What is the expected behavior?
I expect to be able to
- initialize the MSC interface
- deinitialize it
- initialize the CDC interface
etc.
What is the actual behavior?
CDC reports no errors, but does not work.
However if I start with the CDC it works well, so I know my config is correct.
Steps to reproduce.
esp_err_t usb_msc_init( void ){
static wl_handle_t wl_handle = WL_INVALID_HANDLE;
ESP_ERROR_CHECK(storage_init(&wl_handle));
const tinyusb_msc_spiflash_config_t config_spi = {
.wl_handle = wl_handle
};
ESP_ERROR_CHECK(tinyusb_msc_storage_init_spiflash(&config_spi));
mount();
