Re: HSPI Flash programming

Hi,

A new version of flash download tool that can support HSPI flash download mode is estimated to be released this week.

Once it is ok, we will let you know.

Thanks.

Re: Clock Source MEMS

Hi vandiwa,

Please help provide the model and the datasheet for this MEMS oscillator.

The output of the oscillator should be connected to XTAL_IN(Pin28) of ESP8266EX.

Thanks.

Re: ESP8266 工作时很烫,手接触都感觉很烫,请问正常吗?

您好!

请问此处的 VDD_RTC 是否有外接电源?

请注意, VDD_RTC 已由芯片内部 LDO 为其供电,悬空即可,勿需外接。

谢谢!

Re: 遇到一个及其奇怪的问题,ESP8266 应该稳定性有些问题

您好!

请帮忙提供以下信息:

1.ESP-12E 的外部电路连接。

2.使用的是否是官方的固件?版本号多少?请提供贵司测试固件。

另外,请问该模块的电源输出电压为多少,最大输出电流可达多少?出现 exception(0) 检测下电源, CHIP_EN, EXT_RSTB 有无掉电情况。

谢谢!

Re: 8266启动异常

您好!

mode 5 代表 GPIO15/MTDO GPIO0 GPIO2 分别为 101。

所以,此处还需将 GPIO15/MTDO 拉低。

请再试下,如有问题,请反馈给我们。

谢谢!

Re: Waking up from deep sleep without a connection between GPIO16 and RST?

Hi, We test with ESP-12-Q and didn't replicate your issue. After wake-up, the programme runs ok. About deep sleep wake-up, GPIO16(RTC_IO) will give low level signal to EXT_RSTB to reset the module. That's why we request GPIO16 to be connected to EXT_RSTB. Could you please send us your test bin files...
