Pi500 install

[darkhorse]

Hello, I just installed EndeavourOS on a Raspberry Pi500… using a 256GB Samsung Pro Plus A2 class SD card. I’m getting a dmesg log full of “mmc0: running CQE recovery” messages.

I found a note on Jeff Gerling’s site to add a dtparam=sd_cqe parameter to the /boot/config.txt file, since my A2 class SD card should support it. On boot I see the dmesg saying Command Queue Engine enabled, 31 tags.

However, I continue to get a log full of the CQE recovery messages, which I believe is really slowing done my machine.

Any ideas?

Thanks.

dtparam=sd_cqe parameter to the /boot/config.txt file

Doesn’t this only apply for Raspberry Pi OS ?

Ah… looks like CQE is enabled by default. I added dtparam=sd_cqe=off and the error messages went away and things are much faster.

I’ll have to try a different SD card, I’ve just learned that the some Samsung SD cards have had issues with CQE.

If i remember correct all samsung A2 card atm have issues CQ mode

I have succesfully installed EnOS on RPi 5 with a Samsung Pro Plus 128 GB uSD, a Samsung T7 500 GB USB SSD, and a Sans Disk 500 GB NVME.

I also have a couple Samsung Pro Plus 256 GB uSDs. It has been my experience with 256 GB uSD is very sketchy. Not as stable as 128 GB.

I would suggest using a Samsung Pro Plus 128 GB uSD if available. That was been rock solid for me.

Let us know how things turn out.

EDIT:
I support 6 different images that I refresh every 1 to 2 weeks. Every time I do a test install of every image before Release on github. Here is a pic of my work bench with the uSDs I use for testing.

All of them are this uSD

I cannot say how many times these six uSDs have been totally partitioned, formatted, and a fresh install, so far no storage device issues.

i check my note… note is old , i do write down where thread was.

To date there have been no Samsung A2 cards that work with CQ mode - typically because they break when a filesystem cache flush occurs. Therefore they're masked out by that quirk flag (bit 15).

Also flash capacities in datasheets are usually minima - there's a certain number of bad blocks that the manufacturer is willing to tolerate which will vary between each card.

it little long read if interested

@darkhorse i no have access to Pi500

i wonder if you same / close result on Pi500.

on Rpi 5 ( rpi-16k kernel on Arch )

uSD scandisk 128GB extreme Pro

❯ sudo hdparm -Tt --direct /dev/mmcblk0

/dev/mmcblk0:
 Timing O_DIRECT cached reads:   180 MB in  2.02 seconds =  89.22 MB/sec
 Timing O_DIRECT disk reads: 264 MB in  3.01 seconds =  87.85 MB/sec

❯ sudo hdparm -tT /dev/mmcblk0p1

/dev/mmcblk0p1:
 Timing cached reads:   6104 MB in  2.00 seconds = 3055.00 MB/sec
 Timing buffered disk reads: 200 MB in  2.25 seconds =  89.06 MB/sec

same card in usb adapter

❯ sudo hdparm -Tt --direct /dev/sdb

/dev/sdb:
 Timing O_DIRECT cached reads:   180 MB in  2.01 seconds =  89.60 MB/sec
 Timing O_DIRECT disk reads: 256 MB in  3.00 seconds =  85.24 MB/sec

❯ sudo hdparm -tT /dev/sdb1

/dev/sdb1:
 Timing cached reads:   6132 MB in  2.00 seconds = 3068.88 MB/sec
 Timing buffered disk reads: 258 MB in  3.01 seconds =  85.67 MB/sec

Now on Rpi CM5 ( rpi-16k kernel on Arch)

On same card in adapter i get

❯ sudo hdparm -Tt --direct /dev/sda

/dev/sda:
 Timing O_DIRECT cached reads:   300 MB in  2.00 seconds = 149.89 MB/sec
 Timing O_DIRECT disk reads: 322 MB in  3.00 seconds = 107.25 MB/sec

❯ sudo hdparm -tT /dev/sda1

/dev/sda1:
 Timing cached reads:   11366 MB in  2.00 seconds = 5694.36 MB/sec
 Timing buffered disk reads: 200 MB in  1.23 seconds = 162.43 MB/sec

As my CM5 have eMMc i can no test uSD slot ( if i read correct).

if you no mind it interest me what Pi500 return.

I will give it a shot when I get a chance…

Kind of you very… basic same as Rpi 5
Pls forgive reply late , it be a busy day

Here are results on Pi500 using Sandisk 128GB Extreme Pro SDcard default clean install:

Thanks for the feed back. I have not obtained a RPi 500 yet, next month maybe.
Glad to hear the RPi 5 image works without intervention.

If you have the time, inclination, and spare uSD card, here is the procedure for creating an RPi 5 image with btrfs. It will be a few weeks before I can actually test this on a RPi 500.

BTRFS available for EnOS supported ARM devices

It’s official, we now unofficially support btrfs on the EnOS supported Arm devices. RPi 4b, RPi 5. Odroid N2, and Pinebook Pro laptop. The subvol names and their associated mount points have been set up as per the default EndeavourOS settings scheme. See this WiKi entry, https://discovery.endeavouros.com/system-rescue/arch-chroot/2022/12/ Scroll down to this section for details Other mounting examples BTRFS filesystem installs The script that creates the images on github has been enhanc…

Thank for your interest in ARM platforms.
