Deactivate UART completely

Hi, I would like to have my esp32 pcb manufactured and make the first flash myself. All other flashes only happen OTA. So for security reasons I want to deactivate UART completely with die firmware, that will be flashed @ first flash. Can you guys give me a hint, how I can do this? Thanks in advance...

Re: CAN-Bus API multiple filter configuration

To be honest, after reading posts like this + the docs several time, I still didn't understand how to set the filter correctly :oops: I have this code snipped from an example with the comment, that this is a no-filter-config. void can_setRxFilter(void) { CAN_filter = { Single_Mode, 0, 0, 0, 0, 0xFF,...

Re: Wear levelling FATFS performance really slow even for reading?

Important hint:
You have to make sure that there is always only one process/task that is accessing LittleFs at the same time.
Otherwise you will get error-codes, malfunction or even a complete crash.

SPIFFS and FFat are more robust in that cases.

Re: Wear levelling FATFS performance really slow even for reading?

OK fine. I could get it running yesterday and it looks good :) I am using this implementation, because of a very nice esp_spiffs_xxx like API: https://github.com/joltwallet/esp_littlefs First tests: - writing 60kB file in 600ms :) (SPIFFS=800ms, FFAT=9sec) Thanks for that, vonnieda @ESP team: Is the...

Re: anyone using Ubuntu under Windows 10?

No issues at all. Just passthrough the connected USB port to Virtualbox, that's it.

Re: anyone using Ubuntu under Windows 10?

I am using Ubuntu with Virtualbox on a Win10 machine. Without any issues.
Dont forget to configure the number of CPU cores in Virtualbox to use full CPU power during build

Re: Wear levelling FATFS performance really slow even for reading?

Thanks vonnieda! Studied the library, but didn't have time yet to implement it in my project. Could you maybe share your experiences with littlefs regarding writing speed? I my usecase I am writing 60kB logfiles into the flash in ~9sec (FFAT). With SPIFFS the job was done in ~800ms, what was ok for ...

Re: Wear levelling FATFS performance really slow even for reading?

I have a similar problem. I'm saving log files first to a memory buffer then to flash with fatfs. 3-4 KB takes 470 ms :( Same issue... Writing a log file with ~60kB takes ~9sec. During this time I have to block that core completely for the write-task, otherwise it takes even longer. This is disappo...
