#The SDNAND capabilty IDBLOADER_BLOB requires the U-Boot and Linux serial console on UART0
#Linux will hang on reboot if the console remains on UART2

#Note:  IDBLOADER_BLOB is derived from
#  https://dl.radxa.com/rockpis/images/loader/rk3308_loader_ddr589MHz_uart0_m0_v2.06.136sd.bin
#by using the rkdeveloptool to "upgrade" the previous DDR_BLOB loader on the SDNAND
#To recreate it, build the image with IDBLOADER_BLOB unset and boot Rock PI-S in MASKROM mode
#On your host (connected to the RockPi-S's USB-C port):
#  rdeveloptool db rk3308_loader_ddr589MHz_uart0_m0_v2.06.136sd.bin
#  rdeveloptool wl 0 newly_built_image.img
#  rdeveloptool ul rk3308_loader_ddr589MHz_uart0_m0_v2.06.136sd.bin  #this writes 280 sectors

#Then, reset the RockPi-S to boot from SDNAND.  Using that running image:
#  dd if=/dev/mmcblk0 of=rk3308_idbloader_ddr589MHz_uart0_m0_v2.06.136sd.bin skip=64 count=280
