环境:IDF版本为5.1.1,使用的ESP32s3芯片,自己制作的PCB板子
1.使用sdmmc例程,引脚和默认配置相同,使用4线制,初始化时报了如下错误。我对了一下,连线没有错误,请问应该怎么解决呢?

Code: Select all

E (420) sdmmc_common: sdmmc_init_ocr: send_op_cond (1) returned 0x107
E (420) vfs_fat_sdmmc: sdmmc_card_init failed (0x107).
E (420) example: Failed to initialize the card (ESP_ERR_TIMEOUT). Make sure SD card lines have pull-up resistors in place.

是焊接时,esp32s3芯片这一侧有引脚虚焊了!
