Lightweight Installation (SATA HAT only, no cpu fan, no lcd, no buttons)

So it turns out neither RPi.GPIO nor pigpiod are needed to get hardware PWM from the Pi, you can load a pwm kernel overlay and access the BCM2835 hardware PWM directly, see below

https://jumpnowtek.com/rpi/Using-the-Raspberry-Pi-Hardware-PWM-timers.html

I am now using this method and have a simple bash script running the PWM, 0% CPU load compared to the ~7% I was seeing with pigpiod and the ~17% I was seeing with RPi.GPIO

actually for PiGPIO, the 7% was due to alerts and sampling… if u set the flag -m to the service, the CPU load from PiGPIO drops to 0…

but good find though…

It is quite nice, because if you combine this with the lite script that setq wrote, no additional packages are needed to run the SATA Hat and to control the fans.

But for those that need the top hat oled… I think there’s probably a way to change the pwm implementation… doesn’t seem like much change to the code, just the calls would be different… the main arguments Ike dutycycle are largely there already…

Hi all,
great thread. I am looking at doing the very same thing that the op is doing - ie lightweight installation, so this is very valuable :).
@setq would you mind sharing the script you wrote for a minimal install?
Thanks!

Apologies, I forgot the other part of the question, which is can I run the hat without GPIO connections at all, ie with only the USB links between the two? Purpose would be to improve heat dissipation for the Pi.
Thanks.

@tgc The current version must connect to GPIO.

Thanks for the prompt answer @setq, appreciate it. What happens if I don’t connect them? Anything bad hardware wise, or sw just won’t work?
Also I guess I can extend the gpio to increase airflow… Do you know which pins are used?
Thanks!

setq posted the script earlier in the thread, it’s hosted here:
https://rock.sh/get-rockpi-sata-lite

Reading the script you can see that GPIO 26 (pin 37) and GPIO 25 (pin 22) are used to turn on/off the sata controller:

SATA0=26
SATA1=25

You can also see it on the pinout section of the wiki:
Pin 37 (GPIO 26) = SATA 3/4
Pin 22 (GPIO 25) = SATA 1/2
https://wiki.radxa.com/Dual_Quad_SATA_HAT

If you don’t connect the GPIO then it won’t work, those pins turn on the jms561 sata controller. Without the controller the USB bus wont connect to the sata ports .

Perfect, thank you guys!

Hello,
Completed the installation but no joy… All the hw seems to work but lsusb gives me nothing but the root hub.
There is a blue light near the hd I have put in, which turns on and off when stating and stopping the service.
To be clear, I installed nothing at all but the lite script which ran without errors (thanks @setq) - is that enough?
At the moment the hat is on top as it should be, no gpio extension.
What am I missing?
Thanks!

@setq I know you’re going to ask for dmesg… so here you are:

what do you think?

@tgc

It looks like you modified the /lib/systemd/system/quad-sata-lite.service file?

Hi @setq,
No I don’t think I modified … at least not willingly.
This is what it looks like now:
[Unit]
Description=ROCK Pi SATA Hat
Before=local-fs.target

[Service]
ExecStart=/usr/bin/quad-sata-lite.sh on
ExecStop=/usr/bin/quad-sata-lite.sh off
Type=oneshot
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

I also checked that it is similar to the installation script I ran.

Just more info for you, I tested with multiple HDD (both 2.5 and 3.5) in various slots and none work, same symptoms.
I also tested a USB HDD directly on the Pi USB ports and it mounts fine.
Final info during boot the blue lights do flash a few times, then turn solid.

Update, I replaced the bridge with AA cables and some of the drives show up sometimes…
Looks like it was fault of the bridge. Not very happy to waste time for such a simple piece of kit that should be reliable - if that is indeed what it was.

I have to do some testing to see if it all works fine, but @setq can you please let me know which USB on the HAT drives which sata? For example, top USB = SATA 1 and 2.

Final qustion for you @setq, should my service file be any different than in the previous post?

Thanks… we’re getting there.

Yes, top USB == SATA 1 and 2.

It’s the same. Try deleting the Before=local-fs.target.

Brilliant, thanks, I’ll try that.
Fingers crossed it works smoothly now.

I won’t bother going back to allnet for a replacement of the bridge, but I’ll let you know if it is confirmed that it is the bridge, for feedback.

Thanks for the help, @setq!

OK, not quite there.
Problem 1
Sata 1 and 2 work, sata 3 and 4 don’t.
I have swapped cables, linked them to different usb on the pi, try different hdd, nothing to do.
The blue light flashes a couple of times booting but then nothing.

Problem 2
It looks like the disks are recognised on usb 2?

For you @setq attached dmesg with a drive in sata3 for problem 1 and output of lsusb with a drive in sata1 for problem 2.

Thanks for the help !

Ok, update. Finally managed to make it work. The USB bridge wasn’t pushed far enough in, my mistake.

@setq, one question. One of my drives (500 GB Seagate) has a red light on next to the blue one. But it does work fine, apparently. Do you know what is the red light? And how can I diagnose any possible issues the drive ?

@quadnas, I can also confirm that only gpio pins 22 and 37 are required when not mounted on top of the pi. Makes it easy to separate the two boards for passive cooling.

Thanks for the help, much appreciated.

@tgc

When the red light came on, it was the chip that found the error in the hard drive.

You can use smartctl to check the hard disk information, but you need to do two things before that.

  1. Download smartmontools-7.1 (https://sourceforge.net/projects/smartmontools/files/) and compile it. The version in the apt is too old.

  2. Upgrade the firmware (How to upgrade F/W with jms561 under Raspberry Pi). The factory firmware shows something wrong with S.M.A.R.T…
