please keep updates from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/
all firmware for mediatek device would be kept at https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/mediatek
that is a separate tree apart from linux mainline kernel for firmware maintenance.
Had applied the patch allready applied
Used firmware from Banana Pi BPI-R64 open source router with MTK MT7622 64 bit chip design but it is not applied because of error above (same error with ryders/your patch
it looks like you also enabled spi0 if you use the default dts, try to disable spi0 at
spi0 already occupy the same pin 65 you want to software program in shell
https://elixir.bootlin.com/linux/v5.0-rc5/source/drivers/soc/mediatek/mtk-scpsys.c#L248
try to change the line from
usleep_range(12000, 12100);
to
msleep(50);
that is just a experiment to test whether power domain is not ready when bluetooth wants to be active
if issue is still, you can try below several times to see if it is always issue or seldom issue.

How do you get spi0-relationship?
I try gpio56=pin3 spi0 is pin 31,32,36 according to shematic (= gpios 82,64,65)
pin 56 might be occupied by i2c1 if you used the default dts from upstream
you should disable the node before you want to software program that pin
gpio-issue solved so far…gpio was blocked by activated i2c1…so if the special-function is enabled in dts, the direct gpio-access is blocked

@linkerosa have you an idea regarding preloader and emmc?
Hello, I want to attach an SSD and need SATA 3 speed (ie. 6 Gbps). Which of the boards has all these features: Gigabit Ethernet, USB 3, SATA 3 ? Thx
Update: in the following thread someone wrote “The BPI-R2 has two SATA 3.0 Ports / 6 Gbps and not SATA II” ( SATA Performance + Max Disk Size ). But in many product descriptions only SATA 2 is mentioned, also in the Hardware spec wiki ( http://wiki.banana-pi.org/Banana_Pi_BPI-R2#Documents ) it says “Two SATA 2.0 Port”
What is correct?
Regardless if it is sata 3,you will not reach the speed of 6gbit/s. Why does it matter for you?
Btw. This thread is for r64
Hi, I’m just a newbie, don’t know yet the features of the different boards, I wongly assumed the R64 is the successor to R2; it seems it is rather the W2.
I just wanted evaluate the possibilities of building a backup-box to be used in LAN with multiple client-machines to backup, so the LAN and the storing to the SSD should be as fast as possible as this shall be a “realtime” backup solution, ie. always on, though incremental, and it should serve as many clients as possible. So I assumed getting full SATA III speed, but later learned that it’s not a full SATA III like you remarked too. I need to find a cheap HW for this project. Today I found another one (Rock Pi 4 for $39), it looks promising, but it lacks SATA; has only USB3, and not clear yet if one can use Debian on it. It’s not easy to find the right HW for the project as I’m more a SW guy…
imho most SOCs don’t have native SATA-support…i don’t know how it realized on R2/R64, imho as pcie-sata-bridge, where mini-pcie has limitation to 500Mbit/s, so it is not possible to reach sata2/3-throughput…but please make a new thread if needed
for GPIO, how to disable pwm-mapping?
i get this error for pin7 (gpio101):
root@bpi-r64:~# GPIO_NO=$((409+101))
root@bpi-r64:~# echo $GPIO_NO > /sys/class/gpio/export
[ 365.604377] mtk-pinctrl 10211000.pinctrl: pin PWM7 already requested by 11006000.pwm; cannot claim for pinctrl_mt7622:510
[ 365.615703] mtk-pinctrl 10211000.pinctrl: pin-101 (pinctrl_mt7622:510) status -22
-bash: echo: write error: Invalid argument
but nice that here is a message for blocked access
can i disable it from userspace or only in dts?
it seems it is this section in dts:
only pwm7 seems to be defined, why not the others? maybe we can define pwm1-7 (except 3, i’ve did not found on header)
can i use generic pwm-node and define subnodes for pwm1-7?
something like this (of course i have to define the pwmx_pins):
&pwm {
pinctrl-names = "default";
status = "okay";
pwm1{
pinctrl-0 = <&pwm1_pins>;
}
pwm2{
pinctrl-0 = <&pwm2_pins>;
}
pwm4{
pinctrl-0 = <&pwm4_pins>;
}
...
}maybe we can define pwm1-7 (except 3, i’ve did not found on header)
Sure! you could add it if you want to do that.
can i use generic pwm-node and define subnodes for pwm1-7? something like this (of course i have to define the pwmx_pins):
You can take a look at i2c/spi nodes to understand how to add “generic pin configuration” (via function/group) in dts
how can i use emmc? it seems the sd-card-preloader does not work for emmc, atf should be loaded after uboot, but i don’t get into uboot
btw. have not get pwm working yet…also no answer from sean

How did you deactivate i2c?
