Hi Ankit, I've split your question into a new topic, because it's independent from the previous topic. Reset functionality on ESP32 covers a lot of different subjects. The technical reference manual Section 3 (Reset and Clock) covers types of reset. The ESP32 datasheet covers strapping pins which ar...

The ESP-WROOM32 module on the Core Boards currently only supports DIO flash mode. Change the flash mode in "make menuconfig" under "Serial Flasher Config" from QIO to DIO, run make tho rebuild, then re-flash. If using the GUI flasher tool, this option may also need to be changed from QIO to DIO. (No...

Hi Imtiaz, I think the problem you're seeing may be different to the one WiFive has linked, due to the very early failure. Does your ESP32 design have adequate power, including enough capacitance on the power rails (placed close to the ESP32 itself)? If you run "make" instead or "make flash" then es...

How much of a difference does it make? Hi Uhrheber, It really depends on the workload. When reading from flash, quad I/O is almost double the speed (because the data for each read command can be sent over 4 data pins instead of 2). However, because flash contents is cached inside the device the ext...

Hi Kyle, Fortunately not a bug in the documentation, but unfortunately we don't have a timeline for releasing more details or drivers for this peripheral. It will happen, but there are other things we have to complete first. Jeroen posted some high level details here, for anyone who is keen to explo...

Small heads-up: In a day or so esp-idf will be updated with some changes to the esp-idf build system. For anyone creating their own component.mk files, this means some things have changed. The changes are backwards compatible, so you don't have to rush to update your components - but older component...

Just a small additional note, Gigadevice flash (as opposed to WinBond or some other common brands) requires special commands to enter Quad I/O mode. For this reason ESP-WROOM32 currently runs in Dual I/O mode only, however Quad I/O mode support will be added via esp-idf in the near future. If you us...

Hi Kolban,

You are correct that this is wrong. The type signature should be void app_main(void);. It looks like the idf-template and one of the bundled examples needs to be updated to reflect this, I'll do so.

Hello !!!! I am facing the same issue,i have gone through the whole discussion but didn't find the solution. Can you please help me to understand the issue? I have two ESP32s boards and updated the new esptool.py. Hi Peter, Sorry to hear you've hit this as well. I have a few questions to help track...

Do you mean it entered the ROM console while it was supposed to be flashing, or at some later time? It entered the ROM Console first and I tried to flash it then during the boot sequence. 8-( I suppose the boot priority should be program-mode first with GPIO0-Low, no matter GPIO12-High or not. Sorr...
