Title: on A20 board bullseye cannot detect ssd
Post by: dmalik on February 01, 2023, 12:39:45 AM
cfdisk: cannot open /dev/sda: No such file or directory (i boot on sd card with this image http://images.olimex.com/release/a20/ with base or minimal version !)


With boot on sd card with jessie, i can run on the ssd !

Thank's

Are you sure it is sda? Try with fdisk -l to see all listed devices. Did you first mount it before trying to access it?

I tested the base Linux image with a LIME2 board and SSD here and it works fine. The disk I used here was FAT32 formatted and I powered it via the LIME2 board using the sata cable set.

If the issue remains then it is probably something at your side - cabling, powering, disk formatting, etc, etc.

It is not the problem with the Linux image since with the same software I see my SSD. So it is something else that is different between the two Linux images, maybe newer image requires slightly more power? How do you power the SSD and the LIME2 board?

I don't think it's a power supply problem. I booted with a debian 11 for arm (I don't know where I found it)
with the bullseye version of olimex I have
dmesg | grep -i ata1
 ata1: SATA max UDMA/133 mmio [mem 0x01c18000-0x01c18fff] port 0x100 irq 44
 ata1: SATA link down (SStatus 0 SControl 300)
with the other debian 11 version I have
dmesg | grep -i ata1
ata1: SATA max UDMA/133 mmio [mem 0x01c18000-0x01c18fff] port 0x100 irq 44
ata1: SATA link up 3.0 Gbps (Sstatus 123 Scontrol 300)

ata1.00: 117231408 sectors, multi 1 : LBA48 NCQ (depth 32)
ata1.00: configured for UDMA/133


I also found this but I don't know what to do with it. It is beyond my knowledge

I bought the power supply with the A20 micro at olimex : 12v 1A
Title: Re: on A20 board bullseye cannot detect ssd
Post by: LubOlimex on February 10, 2023, 01:53:32 PM
The power supply required can be altered by software means. It is possible that the newer releases are set to require more power (by setting CPU running at higher speeds for example).

We don't have 12V/1A (12W) power supply. We have 12V/0.5A (6W) power supply. And it is insufficient for powering the board and the hard disk.

Your KINGSTON SV300S37A60G hard disk consumes more than 2W when writing (which means 0.4A at 5V). Here are the specs:

https://www.kingston.com/datasheets/sv300s3_us.pdf

Consider another power supply with more amperage.

In the bottom of a drawer I only found a 12v 1.25A power supply
Unfortunately it doesn't work any better
Title: Re: on A20 board bullseye cannot detect ssd

I just received my new power supply : 12v 3A
I can't see the ssd disk any better :
"failed to detect SATA device"

I just changed the sd card with a debian from freedombox. (bullseye 11.0).
here is the fdisk -l[/i]

I  read and write normally on the hard disk!
The original bullseye version of Olimex still does not detect the hard disk

Hmm, this is interesting. Can you post a full boot log from the start, I think there is slight chance that your A20-OLinuXino-MICRO doesn't get properly recognized by the Linux. How is it listed at the start of boot - is it the proper board and board revision listed?

It is probably a software issue but it is very hard to debug this issue when it doesn't exist here. Googling the error you get( "ata1: SATA max UDMA/133 mmio [mem 0x01c18000-0x01c18fff] port 0x100 irq 44 ata1: SATA link down (SStatus 0 SControl 300)) provides a lot of results. Most of them conclude that it is either insufficient supply or improper clock (but we can rule out insufficient supply)

Umm, yes! It appears like the board is recognized as A20-OLinuXino-LIME:

"OF: fdt: Machine model: Olimex A20-OLinuXino-LIME"

And you have A20-OLinuXino-MICRO right? This is a problem. You will need to manually set the board to A20-OLinuXino-MICRO and its exact revision.

You need to interrupt the boot process and stay in u-boot. This is done early in the boot process and you might need USB-serial connection to the board. Refer to chapter "7.1 U-boot tools"

https://github.com/OLIMEX/OLINUXINO/blob/master/DOCUMENTS/OLIMAGE/Olimage-guide.pdf

Let me know if something is not clear.

yes, but look at the same line in the other file and it is recognised as

At what level is it: code on the card or code on the bullseye?
Thanks again for your interest

Yes, in the image that the SSD is not working - the board is improperly recognized. And in the image the SSD is working - the board is properly recognized.

So you have to interrupt u-boot and define the board manually. Refer to chapter "7.1 U-boot tools" from this document:

OK
olinuxino config info say
A20-OlinuXino-LIME-RevA and on my card it says A20-OlinuXino-MICRO RevF !

olinuxino config list say :
I see a long list of names followed by an ID
What should I do
Choose a type that is part of this list? https://olimex.wordpress.com/tag/sata/
with which command?

I was able to read my hard drive with
olinuxino configwrite 9689 f
but olinuxino-sd-to-sata ends its message with
no spi flash found!
Is it possible to boot on the SD card and the system uses only the sata disk
Thank's

In theory it is possible but I don't think we've implemented that function. For the moment the script requires SPI flash. Basically when you boot from SATA the initial boot process starts on the SPI flash and then jumps to SATA.
