Re: After ESP-IDF 1.0...

Ritesh, there is a document which explains silicon bugs present in the first revision of the chip: http://espressif.com/sites/default/files/documentation/eco_and_workarounds_for_bugs_in_esp32_en.pdf Adding to what ESP_Sprite said about using external SRAM in the current revision: It is possible to u...

Re: How to flash the ESP32 ?

There is a "FLASH_DOWNLOAD_TOOL" available for download from Espressif website. Essentially it's a GUI for esptool.py, plus some features to combine binaries and modify them before flashing. You can also use esptool.py itself ($IDF_PATH/components/esptool_py/esptool/esptool.py). Since it is a consol...

Re: RTCWDT_RTC_RESET symptom of what kind of error?

Great to know that it works!
DOUT is already available as one of the modes in menuconfig.

Edit: reading this again, i think you meant adding DOUT as an Arduino option. Yes, we should, once we figure out how to build enough of ESP-IDF in Arduino IDE to make such configuration possible.

Re: 06_sntp example aborts

Hold on! If you haven't erased flash yet, please run this first: $IDF_PATH/components/esptool_py/esptool/esptool.py --port /dev/tty.SLAB_USBtoUART --baud 921600 read_flash 0x9000 0x6000 /tmp/dump_nvs.bin And post /tmp/dump_nvs.bin here. This way we can actually figure out what the bug is :) Afterwar...

Re: Fail to reconnect to AP after deep sleep

At this point I would suggest to disconnect from the AP gracefully: call esp_wifi_disconnect, then wait for SYSTEM_EVENT_STA_DISCONNECTED event, then proceed to enter deep sleep. We do have a plan to implement "maintain AP connection while in deep sleep" feature at some point, but it won't come in t...

Live stream to youtube from China :lol: Yeah, we need cross-continental WiFi for that first.

Re: RTCWDT_RTC_RESET symptom of what kind of error?

Thanks. The files look correct. I have flashed your bootloader to my DevKitC board and unfortunately, it worked fine (if it didn't, troubleshooting would probably be very trivial). Could you please try replacing bootloader.bin file in your "arduino-esp32/tools/sdk/bin/" directory with the one attach...

Re: Question to esp32-cam-demo

Yes, I think I was initially writing this code when only 80MHz clock frequency was available, so I had to skip every other scan line to keep up with frame rate. Regarding I2S interrupt, it gets triggered when given number of samples have been received. The number of samples is written into I2S_RXEOF...

Re: How to flash the ESP32 ?

I mean that you need to make sure that TXD of CP2102 on the DevKitC board goes to RXD of the ESP32 and vice versa. Or just connect them and then try swapping connection if it doesn't work.
