Banana PI Slackware and alternate partition layout

SCerovec · 10-11-2016, 06:52 AM

strange thing:
while in u-boot bot shell i can access and operate the USB devices:

Code:

=> usb reset
=> usb part
=> usb list

all work and evaluate the devices.
Moreover the USB keyboard (called keykoard??) also works - excep the leds don't show CAPS/num no any light?

but after I booted the kernel, any usb device is obscured from me?

Code:

# lsusb -v

yields nothing?

however i have this strange sequence in my dmesg:

Code:

[    0.066981] Serial: AMBA PL011 UART driver

what is pctldev and what those errors mean?

Which Kernel are you using?
Are you using the correct Device tree blob for Banana Pi Pro?
Are you using the correct u-boot for Banana Pi Pro?

I'm using the one I synced from slackware-arm-current as per the HOWTO?

Code:

$ uname -a
Linux banarm 4.7.5-armv7 #2 SMP Mon Sep 26 22:52:36 BST 2016 armv7l Allwinner sun7i (A20) Family GNU/Linux

the other two questions:
No, I use the Banana Pi M1, so i use the bananapi blobs

?

And my best guess is they have some issues here?
is there an easy way i can check which blob is used?

Code:

printenv ${fdtfile}

on the boot loader shell prompt

For some reason I thought that you had a Banana Pi Pro. If you've followed the How to exactly then it should be fine.
You can tell which blob is in use by looking at the config as you have done.

I have 3 Banana Pi's here all installed using the Howto and they all work fine.

I don't know what your issue is I'm afraid!

up there in red

could You please run

Code:

lsusb -v

for me?
apparently the device tree is the culprit?
I did measure all test points and they are all within few percent (1.5 test point yields 1.48V, 5v0 yields 5.23V, USB input is 4.8V)
the plugged device has ~3V on one data lead, all other are 0V.
As the USB devices all resolve on u-boot i assume the dtb/* holds the key?

I have just upgraded to Linux 4.8.1 and testing it has found that USB keyboard no longer works in U-Boot (yet it was previously since I was using it as the desktop test machine!)

I have upgraded to the latest build on the SD Card here, which has restored keyboard access in the u-boot console.

http://armed.slackware.com/tmp/Banan...dfsg1-1.img.xz

I've also found now after upgrading to Linux 4.8.1 that I get nothing on USB either. I'm checking the Kernel configs - it might be that some how the machine I'm using got a botched package upgrade and some how continued to work; and that the Kernel currently shipped doesn't work with USB on the Pi -- which explains your problem!

I'm looking into it.

I can only assume that some how I botched the package upgrades on my desktop -current Banana Pi which is why I didn't notice before now. The primary build machine for -current gets reinstalled regularly, but the desktop test one just gets upgraded.

I'm rebuilding Linux 4.8.1 with the new config and will reinstall both, and probably push out the new packages tomorrow once I've tested them.

WARNING: ALPHA CODE - it will break things, errors are only marginally handled!
patches only are welcome
insufficiently commented patches will be > /dev/null

tested so far:
OTG works
boot.scr works via OTG ("fel-boot")
fel-boot works - reset while holding K3 key
USB works in u-boot (latest stable 2016 here)
auto detection in U-boot works (mostly)
MMC boot works (this script boots my MMC setup)
tftp boot works (only way setup wants to mount /dev/ram is tftp - why?)
fel-boot works for MMC (i boot the USB supplied kernel and run the MMC residing OS)

fel-boot can't mount "root" fs from setup's initrd? yet it mounts from tftp - the same exact files

also i provided a downloadable tarbal with my binary files I tested all with:
fel-setup-01tar.gz ~56Mb

In no way am I to be considered an authority on kernel builds, but so far I found that doing a cross-release config merge is fastest accomplished by hand:

1. run a diff on .configs and examine only changes that might be enabled
2. any changes made that make the "menuconfig" menu structure look odd will probably result in a compile break
3. Probably You'll end up doing something in between oldconfig and newconfig so take the time
4. enabling as few at a time and test-compile is a good idea

Last time i tried to merge a config (4.8 -> 4.7.?) i ended up in abandoning the try all together?
Also it's understood that moving a config is only reasonable on a vanilla kernel

I noticed PCI support on "our" kernel, are there ARM based PCI boards too?

SCerovec · 11-11-2016, 04:51 AM

Update: the banana pi is happily serving as NAS with the 1TB 3.5" HDD in our house:

smb/ftp/ssh

has screen/tmux for torrent sessions
has sbotools and slackpkg for maintainance

I only miss the GBit LAN switch for full feature set now.

maybe there be pictures...
