i just try to read something about dual core variable access.

so everytime one of the cores is reading (or writing) to RAM_buf it have to and when finished and then it should be solved?

I'am sure that there is no protection.

So you are thinking that the RAM_Buf[] is already corrupted by race condition of 2 cores?

i thought that it would be ok when using internal RAM (not PSRAM).

But would i cause a Block swap? How?
What would be the easiest way to block it?

write_buf is the array which should be written to SD Card
RAM_Buf is filled by the second core with readable lines
everything uint16, that there cant be any overflow

Writecounter is the position where the RAM_Buf is filled
ReadCounter is the Position where it is saved to SD Card


#define RAMSIZE ...

Hello,

i have a random Problem.

i'am writing an array of 512 bytes (or 1024, 2048) to a SD Card in SPI Mode.
Sometimes (randomly) 2 of these Blocks are swapped

You can see the swapped blocks in the picture

Hello,

in the past i used the RMT Peripheral for measuring a Pulse length, change this Value and transmit a new Pulse (with new Length).
All this has to be very fast and in IRAM.

Now i wanted to update everything the the actual IDF Version. But nothing is working any more.

Why i cant register a ...
