Hello
What do you want to achieve?
A working initialization and function of the nema-gfx with LVGL V9.3
What have you tried so far?
Initialization with internal nemagfx_pool_mem,
Initialization with external nemagfx_pool_mem in PSRAM,
Initialization with libnemagfx-float-abi-hard.a,
Initialization with libnemagfx.a
LVGL V9.3 without Nema-gfx is is basically operational on the STM32H7S78
Code to reproduce
nema_init();
draw_nema_gfx_unit->base_unit.dispatch_cb = nema_gfx_dispatch;
draw_nema_gfx_unit->base_unit.evaluate_cb = nema_gfx_evaluate;
draw_nema_gfx_unit->base_unit.delete_cb = nema_gfx_delete;
draw_nema_gfx_unit->base_unit.name = "NEMA_GFX";
/*Create GPU Command List*/
draw_nema_gfx_unit->cl = nema_cl_create();
/*Bind Command List*/
nema_cl_bind_circular(&(draw_nema_gfx_unit->cl));
After nema_cl_bind_circular is called, the processor jumps to 0x00000000

Environment
- STM32H7S78-DK
- **LVGL version: 9.3.0 **
- **NEMA Library: from Touchgfx for STM32H7S78-DK **
Has anyone a working version of lvgl on a STM32H7S78 with nema-gfx running, or
does anyone have any idea why the processor jumps to address 0 after calling nema_bind?
The nemagfx_pool_mem buffer RAM is working and correctly initialized.
