Re: Document Requests
Setting SPI_CLKCNT_H too high in SPI_CLOCK_REG register makes in some cases (probably depending on SPI_CLKCNT_N) stop SPI working. This is not documented.

Re: Gripes on ESP32/ESP-IDF
You don't seem to understand the core of this issue but that is OK, I just wanted to illustrate that even Espressif FreeRTOS implementation is not correct (in fact I am quite curious where the issue excatly is). I looked a little into your link and you code. I notice that in your UDP example is bind...

Re: Gripes on ESP32/ESP-IDF
I have prototyped many things with it over this time, using uSD, SPI (peripherals and 5" TFT LCD's) & I2C extensively. Even adding Ethernet capability to it. I have not run into one issue with it. Then you are really a lucky man. While writing my own driver for SPI I have found several issues in ES...

Re: Gripes on ESP32/ESP-IDF
Have you considered the possibility that the problem is at your side? Sure, I have. But then I looked at other manufacturers solution and I can clearly say that the problem is not only me. There are certainly bugs in esp-idf (as in any software), but from your posting one could conclude that it is ...

Re: Gripes on ESP32/ESP-IDF
I think the ESP32 was the labrat or testbech for Espressif, to test FreeRTOS, dual cores, and external RAM, as well as new preripherals. There is a funny/ironic analogy between Espressif products and Windows versios: 8266 -> Windows 7: This actually worked, and kind of still used in many many place...

Re: Gripes on ESP32/ESP-IDF
Again and again... Not only that your hardware is badly designed. You don't even know how to test it and how to write drivers for it. (And your docs are incomplete too) 2 years on the market and your SPI drivers are still not working. 2 years on the market and you still don't know about all HW issue...

Re: Document Requests
AFAIK there is also bug in WP settings (https://github.com/espressif/esp-idf/bl ... ruct.h#L56) both with user commands and SPI flash commands.

Re: Document Requests
bump SPI flash commands
- SPI flash options in SPI registers are not documented (e. g. SPI_FLASH_READ, SPI_FLASH_WREN in SPI_CMD_REG register)
