Re: ESP32 TFT display library

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

Re: ESP32 TFT display library

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.

Toolchain version is not supported

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

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

ESP32 core dump in flash

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...

Re: make erase_flash affects OTA and NVS patitions

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...

Re: make erase_flash affects OTA and NVS patitions

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 i...

make erase_flash affects OTA and NVS patitions

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...
