Hi sorenhl,

200ms is indeed very high latency! Are you able to show us the TCP server code you're running?

LI'd like to be able to not only force a boot from the factory partition, but also either erase the NVS or set a parameter in NVS so the app can make sure it goes back to default settings. So my question is 1) does this GPIO factory boot thing work? and 2) can I access the NVS api from the bootload...

Hi hemant, esp_efuse_mac_get_custom() will read a custom base MAC address which was written to BLK3 of efuse. If you haven't written a custom MAC address, then it won't return anything meaningful. See here for information about setting a custom MAC address . esp_wifi_get_mac() and esp_efuse_mac_get_...

I'd like to hear bit about what the use cases are for OTA bootloader updating. From the ESP-IDF side, we try to keep as much functionality out of the bootloader as possible - for this reason. And we keep IDF backwards compatible with older bootloaders (you should be able to boot an app built from cu...

Hi Jason,

Can you confirm if there's anything unusual environmentally (temperature, etc) with your board? Does the WROVER module have adequate 3.3V power and decoupling capacitors on the power rail?

Angus

No. At least, it's not supported and it's not possible to do so safely. It is technically possible to erase the bootloader sectors and rewrite them from an app ( you may need to disable this option first ), but if there's a power failure or a crash before the process completes then the device will n...

Hi silvingstone,

Looks like a bug. I noticed you also opened this as a Github Issue. I've replied to you there:
https://github.com/espressif/esp-idf/issues/2055

(Please don't report the same thing in two places at the same time, it's confusing! .)

Angus

As WiFive says, any network level functionality should work the same over Ethernet as WiFi. We've recently identified this is a shortcoming in examples (not a lot of Ethernet network examples). Until we release new ones, you can take the code from a WiFi-based network example, remove the WiFi-specif...

Thanks for verifying this Jason. Will get someone from the hardware side to look into this and get back to you.

Thanks Jason. There are some software changes to PSRAM configuration which were merged to the IDF master branch since the commit you have. Are you able to build an updated firmware on some of your problem modules?

If it's still an issue, I'll find someone from the hardware side to look into this.
