Hello, Thanks for your answer. the application is actually stucked, and a few moment later, it restarted, no specific crash indeed.


Hm, there's nothing obvious wrong with the setup you describe. Can you post the stack dump of one of these crashes? Also, can you reproduce this on multiple boards ...

Thanks for the reply. However, there's another similar project which uses those SPI pins as the FLASH model, and it worked fine, that's also confused me a lot. Do you have any other suggestion except those ones?


Those SPI pins (SPICSx, SPICLK, SPID,...) are connected to flash and/or PSRAM and ...

Hello:

Is there anybody who might help on this?

Issue: When PSRAM is enabled, the system crashes during some hardware initialization processes (which then triggers a reboot at the door), affecting the following hardware: LCD, SD, and large files on flash.

🔧 问题描述
当在 sdkconfig 中启用 PSRAM（CONFIG_SPIRAM=y）后，系统在启动过程中初始化某些外设时会频繁崩溃，触发看门狗并不断重启。受影响的外设包括：
* SD 卡（通过 SDMMC 或 SPI 模式访问）
* 从外部 Flash 读取大文件
* LCD 显示屏驱动（通过 SPI 接口）
值得注意的是：在关闭 PSRAM 的情况下，上述所有外设均可单独或协同正常工作；而一旦开启 PSRAM，即使只初始化其中一个外设（如仅挂载 SD 卡），也会在首次 I/O 操作（如 sdmmc_card_init()、f_open() 或 LCD 寄存器写入）时发生死机 ...

Hi,

硬件环境：esp32s3r8+自定义主板
软件环境: idf 5.5.1
问题： 开启PSRAM的系统启动后，会在一些硬件的初始化过程中宕机（然后导致看门口触发重启），这些硬件包括:LCD, SD，flash上面的大文件。
