HI Yeah its almost but not quite like the A20 :) So far I=E2=80=99ve just added the r40 to the following drivers: aw_ccu.c clkng/ccu_a10.c aw_gpio.c aw_machdep.c aw_mmc.c Which seem to do OK. However there are issues with the power chip (axp221) it does get found = by the axp209 driver, but it immediately shuts down and holds NMI active = so that needs work at least, bandaid for now is just disable its IRQ. USB finds the controller, but fails to attach the root hub with = uhub_attach: getting USB 2.0 HUB descriptor = failed,error=3DUSB_ERR_SHORT_XFER The GMAC has trouble finding its PHY. Both could be due to proper power missing I guess. It finds the SATA part and that works quite well (my own ATA stack, not = stock CAM). Haven=E2=80=99t tried video/audio as that has no interest to me for now. --S=C3=B8ren Schmidt sos@deepcore.dk / sos@freebsd.org "So much code to hack, so little time" > On 10 Nov 2018, at 12.12, Emmanuel Vadot <manu@bidouilliste.com> = wrote: >=20 >=20 > Hi, >=20 > On Sat, 10 Nov 2018 11:23:56 +0100 > S=C3=B8ren Schmidt <sos@deepcore.dk> wrote: >=20 >> Hi >>=20 >> I?m looking into getting the BananaPi M2 Berry running, but before I = toss too much time into it I?d like to hear if anybody else is working = on it ? >=20 > R40 just contain most of the IP present in the A20.
