What MCU/Processor/Board and compiler are you using?
What LVGL version are you using?
What do you want to achieve?
Show camera video on the lv_canvus
What have you tried so far?
LV_MEM_SIZE (16U * 1024U *1024U)
While to malloc camera framebuffer, ram overflowed.
Try to set the LV_MEM_CUSTOM as 1 to use ext 16M sdram directly. But there still had the overflow error as :
region ‘RAM’ overflowed by 1078584 bytes
Should I define the ext ram in the file stm32h743.ld to use ext ram directly?
