I assume by "which GPIO are you using", you are referring to IO0 and Reset? I am referring to which IOs are used in the I2C bus(SCL. SDA). Also, I assume you know it's entering the 2nd bootloader because of this line in the logs: entry 0x4008039c. Is that correct? Yes, I think the 2nd bootloader ha...

Hi, I mean that you can improve the ADC task priority and increase the buffer count: int i2s_num = I2S_NUM; i2s_config_t i2s_config = { .mode = I2S_MODE_MASTER | I2S_MODE_TX | I2S_MODE_DAC_BUILT_IN, .sample_rate = 16000, .bits_per_sample = 16, .communication_format = I2S_COMM_FORMAT_I2S_MSB, .channe...

In addition, we can see that the chip are jumping to the 2th bootloader. Can you add some debugging information? It is difficult for us to reproduce your issue. find the function "call_start_cpu0", add some log like this: void __attribute__((noreturn)) call_start_cpu0(void) { ESP_LOGE(TAG, "----%p--...

Hi, cdDave
Which GPIO are you using? What is the GPIO level when it is restarted?

Hi,
Can you make the I2S task run at a higher priority? At the same time you can increase the `dma_buf_count`.

Hi, the read API is thread safe.
Is UART1 and UART2 running at a high baud rate at the same time? So, can you try to Initialize UART1 a UART2 on different core? So their ISR handle will be registered on different cores.

thanks !!

1. 请问 你的 GPIO34 是否已经连接到待测信号,或者是悬空的?

2. gpio_set_drive_capability 是用来设置 GPIO 的驱动能力的

是否可以提供更详细的信息? 比如两块测试板是如何连接的?两块测试板的地线是否共用

Hi,

IO34~IO39 只能作为输入引脚并且没有内部上拉功能. 所以需要外接上拉电阻.

谢谢 !!

Hi
请检查 IO0 上是否有电容, 作为 CLK 输出 pin 的时候最好 IO0 上没有接电容, 这会影响时序.

谢谢!!
