Write to an A1-rated Micro SD card failed
#11
I've recently spent a lot of time debugging this issue, but unfortunately there aren't too many interesting new findings.  Also, spending some time on the #pinebook channel and disussing this issue with other people made it clear what to try first.

Before doing anything else, I wanted to make sure that the kernel doesn't unnecessarily limit the power consumption of microSD cards in the PineBook Pro.  An external regulator, Powtech PT5108, provides power to microSD cards in the PineBook Pro, so the DesignWare MMC IP core is unable to know the max. current that can be supplied to microSD cards.  As a result, mainline kernel tells the cards to limit their power consumption and to operate in low-power mode by setting the XPC bit to zero, while the PT5108 is capable of delivering 500 mA.

A quick-and-dirty kernel patch made the actual current limit known to the MMC driver, as a hardcoded value, which is visible from the kernel messages below, generated by the patched kernel upon inserting a Kingston SDCS2/16GB A1-rated card:

Code:
[  103.714270] MMC DEBUG: voltage: 262144, max_current: 0 (calculated in sd_get_host_max_current())
[  103.714311] MMC DEBUG: max_current: 500 (forced in sd_get_host_max_current())
[  103.714323] MMC DEBUG: max_current: 500 (fetched in mmc_sd_get_cid())
[  103.835082] MMC DEBUG: voltage: 262144, max_current: 0 (calculated in sd_get_host_max_current())
[  103.835122] MMC DEBUG: max_current: 500 (forced in sd_get_host_max_current())

[  103.837035] mmc_host mmc1: Bus speed (slot 0) = 148500000Hz (slot req 150000000Hz, actual 148500000HZ div = 0)

[  104.317123]  mmcblk1: p1 p2

The end result is that the patched kernel configures the microSD card to consume up to 400 mA (translated into a #define, one of the kernel messages above actually means "current_limit: SD_SET_CURRENT_LIMIT_400"), and to operate in normal/high-performance mode (XPC bit is set to one).

All this made no difference to the linear write speed or reliability of the Kingston SDCS2/16GB card in my ISO PineBook Pro.  Surprisingly, the SDCS2/16GB card works just fine in my first-batch ISO PineBook Pro, with or without the above-described kernel patch, while it refuses to work correctly in my ANSI PineBook Pro, while runinng the unpatched kernel.  I haven't tested it in my ANSI PineBook Pro with the patched kernel.

Next, I tested a Kingston SDCE/32GB A1-rated high-endurance microSD card in my ISO PineBook Pro, with the patched kernel.  Unfortunately, the SDCE/32GB still didn't work, and the patched kernel spitted out the following error messages upon inserting the SDCE/32GB card and attempting to write a few GBs of data to the card:

Despite the fact that setting the cards to operate without unnecessary power limits yielded no visible results, I might implement a kernel patch that properly supplies the current limit of the external regulator to the MMC driver using a Device Tree parameter, etc.  Anyway, that's the right way to configure the microSD cards, instead of unnecessarily forcing them to throttle their power consumption down.

During the testing using my ISO PineBook Pro, I've also somehow managed to get failed writes on the Kingston SDCS/16GB card, which is not A1-rated and is the only card that works correctly in my ANSI PineBook Pro.  So, there's the SDCS/16GB that always works in my ANSI PineBook Pro and occasionally fails in my ISO PineBook Pro, and there's the SDCS2/16GB that never works in my ANSI PineBook Pro and always works in my ISO PineBook Pro.  That's really weird. Sad

The weirdness I've experienced in the failed writes probably means that the root cause of this issue lies much deeper, causing pretty much random incompatibilities between different microSD cards and the MMC devices in PineBook Pros.  The same probably applies to the RockPro64 and, possibly, to some other SBCs.  Such random incompatibilities shouldn't be present at all, at least not in theory.

Another issue I've noticed is that UHS-I microSD cards don't work in the ultra high speed mode when a PineBook Pro is booted from such a microSD card.  Instead, they end up working in the high speed mode.  If the same PineBook Pro is booted from the eMMC module and the same microSD card is inserted later, the card is properly configured to work in the ultra high speed mode.  Here are the related kernel messages when a PineBook Pro is booted from a UHS-I microSD card:

As a side note, forcing the MMC device to not operate in the ultra high speed mode, using the available Device Tree settings, makes the Kingston SDCS2/16GB card work just fine in my ANSI PineBook Pro, for example.  That just adds to the overall level of weirdness.

I tried 3 different SD cards I had laying around, all of them are A2:


1) ADATA "High Endurance" A2/V30/U3/XC1 64GB


Code:
[155877.964017] mmc_host mmc1: Bus speed (slot 0) = 148500000Hz (slot req 150000000Hz, actual 148500000HZ div = 0)

[155878.362737] mmcblk1: mmc1:59b4 SD    58.9 GiB


Code:
❯ sudo dd if=/dev/zero of=/dev/mmcblk1 status=progress iflag=fullblock oflag=direct bs=1M count=1024

2) ADATA  A2/V30/U3/XC1 64GB

Code:
[156291.925259] mmc_host mmc1: Bus speed (slot 0) = 400000Hz (slot req 400000Hz, actual 400000HZ div = 0)

3) SanDisk "Extreme" A2/V30/U3/XC1 256GB

Code:
[156491.253398] mmc_host mmc1: Bus speed (slot 0) = 400000Hz (slot req 400000Hz, actual 400000HZ div = 0)

1024+0 records out
1073741824 bytes (1.1 GB, 1.0 GiB) copied, 19.0605 s, 56.3 MB/s


All of them completed without errors in dmesg. This is with the 5.13.5 kernel on postmarketOS (mainline kernel + a handful of patches from manjaro's kernel to fix some usb-c stuff, nothing more)


Edit:
I found an A1 SD card which worked without errors when dd'ing 1GB to it.

4) TeamGroup Pro A1/V30/U3/XC1 256GB:

Code:
[157288.317875] mmc_host mmc1: Bus speed (slot 0) = 400000Hz (slot req 400000Hz, actual 400000HZ div = 0)

Thank you very much for testing these microSD cards out!  This just confirms that not all A1-rated cards refuse to work, but it also cannot lead to a conclusion that all A2-rated cards work fine.  Hmm, what a conclusion. Smile

As already noted on the #pinebook IRC channel, I'll create a kernel patch that exports as much data about an SD card as possible, and we'll revisit the testing with that utility under our belt.
