@Kisszalimo, while I don't have pinetime watch to verify that it works, here
is what you may try:
There is pending PR #3063 that adds options that can tweak LVGL a little bit
so it will fit in memory.
You could merge commits from this PR to your mynewt-core branch.
I hope PR will be merged soon.
Next you can change you target syscfg.yml to have this:
```yml
syscfg.vals:
LCD_ITF: spi
LCD_SPI_DEV_NAME: '"spi0"'
LCD_SPI_FREQ: 8000
LCD_SPI_MODE: BUS_SPI_MODE_0
LCD_CS_PIN: 25
LCD_RESET_PIN: 26
LCD_DC_PIN: 18
LCD_BL_PIN: 13
LVGL_DISPLAY_HORIZONTAL_RESOLUTION: 240
LVGL_DISPLAY_VERTICAL_RESOLUTION: 240
LVGL_ST7789: 1
# this reduce memory usage of LVGL
LV_MEM_SIZE: 40000
```
I did test it on **nordic_pca10040** target that has same MCU but no other
peripherals except LCD
