Re: Cannot download through Flash Download Tools

Hi,

The schematic is ok.

Please help confirm current problem is for ESP8266 and ESP8285 is ok.

When you use ESP8285, have you moved the external spi flash and choose spi mode as DIO?

Could you please double check the part Number of the flash on this test board? W25Q32?

Thanks.

BTW, we cannot open the the link that you provided. So, If you have some questions about internal MCU of ESP826EX, you can list them and we will try to answer.

Thanks.

Re: ESP8266 IoT Ref Compatible Board

Hi,

ESP8266EX does not support the hardware debug tools, so you need to debug by add log print through UART.

You can use minicom or other uart program to check the log.

More questions, please let us know.

Thanks.

Re: WROOM-02 Resetting

Hi,

R=10Kohm and C=10nF for EXT_RSTB is recommended. You'd better also add RC(5K+100nF) in EN pin.

What the maximum output current of your power supply?

BTW, could you please send us the photo of your test environment for checking?

Thanks.

Re: ESP8266 IoT Ref Compatible Board

Hi,

The bin that you added in flash download tool is not right. The directory should be as shown below and format of firmware should be .bin, not bin_rep.

D:\VM\share\ESP8266_NONOS_SDK_V1.5.3_16_04_18\ESP8266_NONOS_SDK\bin\at\512+512

Please try again.

Thanks.
