Re: Use of dual core

Nothing yet, sorry, haven't been able to come around to looking into this.

Re: esp32使用emac时,gpio0作为EXT_OSC_CLK,如何避免进入下载模式

I'm gonna respond in English; if you cannot understand the explanation because of that please tell me and I will have someone translate it into Chinese. Just to check if I understand it correctly: You have an external 50MHz clock source and want to feed that signal into GPIO0 to feed the Ethernet MA...

Re: Coredump info is incomplete

It looks like for some reason, dumping the core took long enough for a watchdog to trigger. We merged a fix for that bug three days ago; can you try pulling esp-idf and then see if the problem is still there?

Re: Deep sleep power consumption - has something been changed in the latest ESP_IDF release?

Not entirely sure if that wasn't the case earlier on, but we keep the fast RTC ram powered now, in order to quickly resume after a wakeup event (to work around a bug in the current silicon). You can disable that by adding esp_deep_sleep_pd_config(ESP_PD_DOMAIN_RTC_FAST_MEM, ESP_PD_OPTION_OFF); in yo...

Re: ESP32 Webradio

Could be, yes. We should get the new silicon this week, I guess general availability won't be too far off from there.

Re: Problem while writing into SD card

Aye. The explanation is that in C, the end of a string is indicated by a zero byte. So if you feed e.g. a string containing '0x01 0x00 0x02 0x02' to fprintf, it will think it is actually a string only containing 0x01.

Re: ESP32 Webradio

Fancy! Wrt APLL jitter: The driver actually does not use the APLL at the moment; it divides down an internal 160MHz signal using a fractional divider. This causes the jitter you see. I'm asking around if we have example code to configure the APLL somewhere; although there's a bug in it for the first...

Yo will need to make sure the level on GPIO0 is high after reboot, otherwise the ESP32 enable download mode. Are you sure that whatever you have connected to this pin doesn't also pull it low when the ESP32 is reset?

Re: ESP-WROOM-32 AT commands firmware

Keep in mind that that is a preliminary version of the binary. We may or may not support bugs in this until the official version comes out.

Re: link for released AT bin

Fyi: the AT binary isn't available yet because it isn't production-ready. The current AT firmware is compiled with a non-production version of ESP-IDF; apart from that there's also a bug related to AT+RESTORE that we need to fix. We'll edit the git repo to kill the non-working download link for now;...
