Hello @kisvegabor
Upon using lv_refr_now() in my application, I’m getting hard fault.
I have captured stack traces for 3 tries.
Find the attached files for your reference.
tft.c (6.9 KB)
tft.h (712 Bytes)
lv_conf.h (25.2 KB)
Also note, I’m using SW rotation using lv_disp_set_rotation(our_disp, LV_DISP_ROT_270);

Hi,
What happens if you set LV_DISP_ROT_MAX_BUF 4*1024?
Currently it’s set to 20*1024, you want to try with 4*1024?
It seems you don’t call lv_disp_flush_ready. Could you check it?
I checked, its already being called in DMA_TransferComplete() Callback. Do I still need to call it?
Actually, I have already used this function earlier in another project but without software rotation and worked fine.
Nope, it’s enough to call it once. I was asking because on the last screen shot it was waiting for this function to be called. But maybe it was just a coincidence.
Anyway, it seems like like something is really wrong with software rotation. Can you reproduce the issue in a simulator?
Actually, I directly test GUI on a STM32 hardware and currently won’t be able to try it on a simulator due to the hectic schedule. It’ll be better for me to work around on a hardware.
And let me know If any other input is needed.
To move forward it would be required to reproduce it in the simulator. Did you have time for it?
