Description
I am running out of RAM on my teensy 4.1 and need to align some image buffers into either DMAMEM or EXTMEM, but in order to do that I need to understand where the buffers are stored for images that are accessed via the SD card.
I have successfully moved my canvas buffer into DMAMEM, but not sure where the buffers are located for images read from an SD… be it jpgs, png’s or BMP’s.
What MCU/Processor/Board and compiler are you using?
Teensy 4.1
What LVGL version are you using?
8.3
What do you want to achieve?
Move image buffers to DMAMEM or a QSPI device
What have you tried so far?
Example of canvas to DMA mem:
DMAMEM static uint8_t cbuf[LV_CANVAS_BUF_SIZE_TRUE_COLOR(320, 240)]; //Need to implement the same sort of thing for images read from an SD card
Code to reproduce
N/A
