M1s dock SDK issues with DBI for LCD

I am trying to run lvgl demos included in sdk on NT35510 display. So far I managed to add missing referenced not quite updated with most recent SDK but I also needed to add definitions for BL808 DMA support
in file drivers\lhal\include\bflb_dma.h I added following:

(line 166)

#elif defined(BL808) || defined(BL606P)

/* @defgroup DMA_PERIPHERAL_REGBASE dma peripheral data register address definition*

nothing happens after flashing…

other displays like ILI9341 (SPI) work fine

Please help with that issue

Thanks
