请问用的是什么芯片？晶振的型号是？具体有做什么操作吗？

esp32c3, FC-135, RTC_CLK_SRC设为External 32kHz crystal
怎么都不起振

Sounds good, I'll take a check, thank you.

Yeah, I'm using that example, and already tried the f_getfree code, which don't work( got both 0 size)
I also tried to use 1: or 2: instead of 0: in f_getfree, they would make the program crash.

Any ideas?

Thanks for replying.

Forgot to mention, BLE is also enabled, I'm using bluedroid, CONFIG_ESP32_WIFI_SW_COEXIST_ENABLE is set to yes.

I'm using esp-idf 4.4.2, sd card is on SPI, fatfs mounted.
How to check it's free size?
I tried example_get_fatfs_usage in ext_flash_fatfs example, it don't work.

I want to suspend wifi to save power and recover it when I need, how to do that?
esp_wifi_stop works to stop it, but when I tried esp_wifi_start to recover wifi link, it don't work.

问题暂时回答不了可以理解，但好歹给个回复行不行？

试过ext_flash_fatfs例子里面的example_get_fatfs_usage，能过编译但不工作，盘符改成1也没用

卡上已有fatfs

好像找不到
