When I look at the likes of: https://github.com/raspberrypi/firmware/tree/master/boot I see two *-rpi-2-b.dtb links on the page, each referencing one of: https://github.com/raspberrypi/firmware/blob/master/boot/bcm2709-rpi-2-b.dtb https://github.com/raspberrypi/firmware/blob/master/boot/bcm2710-rpi-2-b.dtb It appears to me that bcm2709-rpi-2-b.dtb is for RPi2B V1.1 and before (cortex-A7 based) and that bcm2710-rpi-2-b.dtb is for RPi2B v1.2 (the cortex-A53 based variant). I base this on: https://www.raspberrypi.org/forums/viewtopic.php?t=238262 and its table: 2708/2835: Pi Model A, Model B, A+, B+, Zero, Zero W, Compute Module 2709/2836: Pi 2B 2710/2837: Pi 3B, 3B+, Compute Module 3 mixed with: https://www.raspberrypi.org/documentation/hardware/raspberrypi/ and its outline: • BCM2836 • The Broadcom processor used in Raspberry Pi 2 • BCM2837 • The Broadcom processor used in Raspberry Pi 3 (and later Raspberry Pi 2) If that is correct, then the -r364053 is using the cortex-A7 variant's dtb instead of the cortex-A53 variant's dtb. It looks like it should be using bcm2710-rpi-2-b.dtb to be treating the RPI2B v1.2 in an RPi3B like way. === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar) _______________________________________________ svn-src-head@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
