WRT: use esp-idf-tools-setup-1.2.exe, over esp-idf-tools-setup-2.0.exe I would also like to understand if ". . .2.0.exe" can be used for building esp-idf v3.3 or not. Else, considering v3.3 is LTS but CMAKE toolchain is "preview" only; is there a plan to support v3.3 and v4.x with the same version ...

Seeking confirmation on the following items: (else otherwise) 1. Each ESP32 device* has WIFI_MAC_Address (56-bits=48-bit MAC Address + 8-bit CRC) uniquely programmed at factory. (*not the module, the IC itself) 2. For MAC address in eFuse "24:0A:C4:HH:MM:LL" total of four MAC addresses ":LL", ":LL+1...

preview - not confirmed - wait for confirm

How long of a wait ? Need this info to finalize PCB design

Yes, EXACTLY SAME

I have noticed following differences in pin assignments between the 6mm x 6mm QFN48 and 5mm x 5mm QFN48. Referring to ESP32 Datasheet V1.2 Fig 2 on pp 6 and Fig 3 pp 7. So it will be useful to get confirmation on these items. It would be much better if section 2.2 "Table 1 : Pin Description" is upd...

Yes, it is a known issue. The boot code in the ROM of the ESP32 isn't directly compatible with the specific instructions the flash chip needs to use QIO mode. We are working on a workaround, expected to get into esp-idf in the coming weeks, but for now, QIO mode does not work here. Is there any upd...

Thanks for the confirmation regarding QIO mode support. 1. Is DIO @80MHz tested on DevKitC (ESP-WROOM-32)? 2. Can you kindly list the target device families from GigaDevice and Winbond for which QIO mode will be supported? 3. For the planned feature support on this matter, will SPI Flash devices wit...

I tried to configure QIO/40MHz operation (using menuconfig), and I see the following on UART0-console: ets Jun 8 2016 00:22:57 rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) flash read err, 1000 Falling back to built-in command interpreter.

With the latest SDK and tools, I noticed the following issue: At Line #432 and #433, the toolchain version verification returns a null string. TOOLCHAIN_COMMIT_DESC := $(shell $(CC) --version | sed -E -n 's|xtensa-esp32-elf-gcc\ \(([^)]*).*|\1|gp') TOOLCHAIN_GCC_VER := $(shell $(CC) --version | sed ...
