I was able to console in with the HAT attached.

Ok, I got it booting, so I did: set devtype nvme set devnum 0 set distro_bootpart 0 set prefix /boot/ load nvme 0:0 $loadaddr /boot/boot.scr source Doing a printenv before I see: => printenv arch=arm baudrate=1500000 board=evb_rk3568 board_name=evb_r_targets=mmc1 mmc0 nvme scsi usb pxe dhcp spi bootcmd=bootflow scan -lb bootdelay=1 bootp_arcNDI:003000 cpu=armv8 cpuid#=54434e4b383000000000000000070d19 dnsip=192.168.1.253 eth1addr=1e000 ethaddr=1e:f2:d5:f1:74:04 fdt_addr_r=0x12000000 fdtcontroladdr=7ded3a80 fdtfile=rockchipr=0x12100000 gatewayip=192.168.1.254 hostname=rock-3a ipaddr=192.168.1.253 kernel_addr_r=0x00 kernel_comp_size=0x8000000 loadaddr=0xc00800 netmask=255.255.255.0 pxefile_addr_r=0x00e000offset_f=0xffe000 script_size_f=0x2000 scriptaddr=0x00c00000 serial#=09103e09ce4edd27 serverserial@fe660000 stdin=serial@fe660000 stdout=serial@fe660000 vendor=rockchip Environment size: 916/126972 bytes So this is not finding the boot.scr with the bootflow scan -lb, so now is time to make it boot automatically.

@Sarang He Try these images https://github.com/NickAlilovic/build/releases/tag/20250306

Ricardo put some real effort into Rk3528 here :https://github.com/armbian/build/pull/9102 Since the 2A/2F are using the same SoC this should actually help a lot.

@Thịnh Nguyễn: pls give me link to download, I also have tv98. Thank you
