Unfortunately my logic analyzer does not measure accurately up to these speeds.
So by trial and error I found that 32MHz instead of the 40MHz (first release) works reliable for this ER-TFTM035-6 display.

Thx for your help

Thx,

For the hint, my settings were okay however: decreasing the SPI speed was the solution for the issue. I will measure the SPI speed (first and now) later and see where the difference is.

Hi Loboris, After using the "first" TFT display library since several months I want to switch to the latest version. Settings: - using the latest esp-idf - the correct commit - same display / pinout - same type of display and resolution - correct setting of menuconfig - No compilation issues After f...

Hi, According the readthedocs I used: ESP32 toolchain for Linux is available for download from Espressif website: • for 64-bit Linux: https://dl.espressif.com/dl/xtensa-esp32-elf-linux64-1.22.0-61-gab8375a-5.2.0.tar.gz This should be: https://dl.espressif.com/dl/xtensa-esp32-elf-linux64-1.22.0-73-ge...

Hi Guys,

Just setup a new toolchain; following the ESP32 guide, and the result is:

Toolchain version is not supported: 1.22.0-61-gab8375a
Expected to see version: 1.22.0-73-ge28a011

Make menuconfig is oke but xtensa-esp32-elf-1.22.0-61gcc: not found,
Any idea?

In my application I get infrequent errors due to input from mqtt messages. I have two similar esp32 setups running which show the error at the same time. As it can take several days before an error occurs I try to catch it in flash to find the origin. Have an issue using the core dump in flash. My m...

Thks for your reply Kolban, The erase_flash is for development only. In case you change partition sizes it's possible that some data remains. I used it initially to erase the flash when a runtime error in a program occurred. (If I remember correctly I could not flash to ota_0 at that point.) There i...

Is there a convenient way to only erase both ota partitions. E.g. an "erase_flash_ota" "coupled" to all ota partitions only. I thought about flashing an empty image in ota_0, store this empty image also on the web server. Load the target image in ota_0. Let ota_0 load the empty image in ota_1 etc. B...

I can' t find the exact scope of the make erase_flash command in the documentation. From tests is looks like it erases all of the flash? The application had two custom OTA partitions, uses NVS to store data and SPIFFS storage. Unfortunately it erases the NVS partition I use to store data. Is there a...
