WROVER-B - PSRAM + SPI SD card Guru meditation

[marmou]

Good afternoon.
I'm starting work with PSRAM because I need lot of memory for program language modifications during the array of char arrays.
Examples on net are only few and don't right what I need, but at the end I made something which works/don't works.
For filling of array I use TextText.txt which is attached.
HARDWARE: LilyGo TTGO T-call & PMU (WROVER-B)
PROGRAMMING IDE: Arduino IDE and PROGRAMINO (https://programino.com/)
OS: Windows 10

Here is the code:

Do You have please any idea what can be the reason of these errors ?
Thank You.

[lbernstone]

If you decode the backtrace (https://github.com/me-no-dev/EspExceptionDecoder) it will show you exactly where the watchdog timer is getting stuck. I can see that you have 2 tight while loops reading from flash. Put a delay(1) at the end of each of those loops and it should keep the watchdog happy.
I would also recommend you read the data in chunks of 512 bytes (or the sector size if it is larger) to maximize the transfer rate.

[marmou]

Good mornng.
I tried put to each cycle of while delay(1); and also at the end of while loop delay(10);. Still the same issue at the same place.

Decoder give mi this feedback:

Unfortunately, I do not understand this.

Is there any cache, which must be cleared ? Is necessary close file and open it again ? Or switch off SD card and mount again ? I don't know how it works inside.

[ESP_Sprite]

I'm 80% sure you're overflowing a buffer somewhere, but the foreign-language functions and variables throw me off enough that I can't decode what your program is doing.

[marmou]

SOLVED, WORKS !
Like a size must be used size of char pointer, not char, because it is array of char type pointers.
How I read this again and again...
ps_calloc(PocetRadku, sizeof(char*));
ps_calloc(DelkaRadku, sizeof(char*));
