Hi Noor,
I successfully applied this patch, built and ran a couple of samples on my
RPI4b. I ran unlimited and ticker. I'm going to try one of my applications
later today or tomorrow.
The build has one warning:
../../../bsps/aarch64/raspberrypi/start/bspstarthooks.c: In function
'bsp_start_hook_1':
../../../bsps/aarch64/raspberrypi/start/bspstarthooks.c:51:3: warning:
implicit declaration of function 'raspberrypi_4_setup_mmu_and_cache'
[-Wimplicit-function-declaration]
51 | raspberrypi_4_setup_mmu_and_cache();
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../../../bsps/aarch64/raspberrypi/start/bspstarthooks.c:51:3: warning:
nested extern declaration of 'raspberrypi_4_setup_mmu_and_cache'
[-Wnested-externs]
Thanks!
Alan
