Re: Different stress tests producing different results?
I've not run any prolonged pounding of my 4B (a v1.1 2GB unit), but have been able to run at 2 GHz (and force_turbo=1) 24x7 for about 4 months now, without a single burp, in my normal use. I have a heat sink/CPU fan-combo installed, and normally see temps ranging from mid to high 40's (C) at light l...

5.4.72-v8+ has kernel APPARMOR and AUDITD, but no SELINUX :(
Hello, group - I had noticed a couple weeks ago that a recent update to my 4B (performed via "apt upgrade") had both APPARMOR and AUDITD support compiled into the kernel, in both 32-bit (arm_64bit=0) and 64-bit (arm_64bit=1) mode. This is on the legacy 32-bit user-space version of Raspbian...

Re: Is there a published list of CM4 Revision Codes?
That list of revision codes was never intended to be comprehensive or real time updated. For example, I never know when a new manufacturer comes online, which of course means a new revision code. Also when a board revision changes, I'm not necessarily going to know. Again, fair enough. :) The impor...

Re: Is there a published list of CM4 Revision Codes?
:: snip :: cormack just wants some example revision codes for the CM4 like the others in the table at the end of the revision code document. He's not asking for the actual SKU. This is correct. I fully expect there will be other files, commands, or other mechanisms available to detect the differenc...

Re: Is there a published list of CM4 Revision Codes?
I guess you're looking for something like the part number embedded somewhere? e.g. CM4102000 CM4WRREEE CM4 (WiFi) (RAM) (EMMC) Incorrect. I was looking for "Revision Codes", like the ones published on the two links in my original post. The code revealed when you run "cat /proc/cpuinf...

Re: Is there a published list of CM4 Revision Codes?
There is no if. It does use the same revision code scheme as the CM4 and Pi 400 were added to the list of types. There doesn't seem to be any urgency to updating the example revision table at the end though as the Pi 4 v1.2 revision was only added via a pull request by Dougie. Only the beta testers...

Re: Is there a published list of CM4 Revision Codes?

Re: STICKY: USB-MSD boot EEPROM third update - 2020-06-15
I found that Raspbian and hopefully the new Raspberry OS (32bit) support TRIM via the mounting of the SSD in fstab using the "discard" option. I wonder if that works and precluded the need for manually running the fstrim command periodically? You can avoid putting the "discard" ...

Re: STICKY: USB-MSD boot EEPROM third update - 2020-06-12
I've been banging away at my system all weekend, and couldn't be happier with where things are. Everything has been working fine on my Pi 4B 2GB v1.1 board, with SupTronics X820 V3.0 SATA III board and Samsung 860 QVO 1TB SSD. I believe I'm as up to date on everything as can be, if I've been followi...

If you do have working TRIM, you can enable the weekly fstrim.timer service with sudo systemctl start fstrim.timer and check the status with sudo systemctl status fstrim.timer (using the weekly fstrim service is better than adding discard to the mounting options). Doe this service work for all file...

Re: USB-MSD boot EEPROM update - 2020-05-28
Format the SSD the same way as an SD card. A 256MB FAT partition followed by an EXT4 taking the rest of the drive, unless you want something a separate data partition. Be sure to point the root= in cmdline.txt to the SSDs EXT4 partition and edit /etc/fstab to mount the correct partitions. And the f...

I'd still like to find out where I went wrong with the recovery.bin file, though. :/ Did you extract the 2020-05-28 zip into /lib/firmware/raspberrypi/bootloader/beta? If so then you overwrote recovery.bin as well and that would have made the file hash different. recovery.bin was updated because of...

Looks like I wound up with the wrong recovery.bin in my beta directory now. I haven't figured out the recovery.bin either. I've gotten to not replacing it (I do use the new supplied one if making up a standalone SD card for flashing something new). You can also use '-i' to ignore the checksum error...
