PWM problem

[krzysztof....@gmail.com]

Hello,

I want to use PWM pins by Adafruit in my BBB but I have got some problems. Below some info about my soft:

root@beaglebone:~# cat /etc/dogtag
BeagleBoard.org Debian Image 2018-06-17
root@beaglebone:~# cat /etc/debian_version

root@beaglebone:~# uname -a

root@beaglebone:~# pip install Adafruit_BBIO
Requirement already satisfied: Adafruit_BBIO in /usr/local/lib/python2.7/dist-packages/Adafruit_BBIO-1.0.10-py2.7-linux-armv7l.egg

when I want 
 install bb-cape-overlays  I get:

bb-cape-overlays is already the newest version (4.4.20180914.0-0rcnee0~stretch+20180914).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 ti-opencl : Depends: libtiopencl1 (= 01.01.15.03-git20180817.2-0rcnee4~stretch+20180817) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

You have an old version of u-boot in the eMMC:

Please run this script to help verify where it's located so we can remove it..

Humm, looks like i need fix my logic, it didn't find the MLO file in p1:

[ 1.348526] mmcblk1: mmc1:0001 MMC02G 1.79 GiB
[ 1.348957] mmcblk1boot0: mmc1:0001 MMC02G partition 1 1.00 MiB

[ 1.349736] mmcblk1rpmb: mmc1:0001 MMC02G partition 3 128 KiB
[ 1.351791] mmcblk1: p1 p2

But otherwise, this 'should' fix it..

sudo dd if=/dev/zero of=/dev/mmcblk1 bs=1M count=100

and reboot..

Background, we moved overlays from the kernel to u-boot, thus a
"recent" u-boot must be present for this to work properly, in your
case, you have an old version of u-boot, we couldn't even detect..

Do you remember what version was installed the eMMC? Then i can work
on patching my version.sh script..

[Krzysztof Śmiałek]

Hi,

on the eMMc I have installed this one:

https://debian.beagleboard.org/images/BBB-eMMC-flasher-debian-7.5-2014-05-14-2gb.img.xz

Becouse I didn't find any newer for 2gb version. It will be easy to come bac this changes? :)

sudo dd if=/dev/zero of=/dev/mmcblk1 bs=1M count=100

Becouse when I last time use it I need to reflash board ;P

[Krzysztof Śmiałek]

I used this and BBB don't want to boot after reboot;/ so the same situation like yesterday with this comand. Without card the same. Pressing boot buton didnt help. Hmm...

Thanks, flashing and old A5A now..

Yeah, if it's from 2014, there's a good chance it won't auto boot the
microSD, just too old of a version of u-boot..

Yes, there is a limited number of images that will fit in the 2GB
eMMC.. Best bet is just the console one, or just use a big microSD
card.

[Krzysztof Śmiałek]

Ok, so what should I do? Reflash emmc to old one once again? When I was testing yesterday after reflashing the pwm was working on this old soft but probably it will be better if i can use new version of soft.

It's up to you.. but i'd just run:

sudo dd if=/dev/zero of=/dev/mmcblk1 bs=1M count=100

and utilze the new microSD image.

[Krzysztof Śmiałek]

Ok,

so first of all I need to run the BBB from emmc? So I need reflash this bootloader, yes?

After that I need download new version of image from side, load on sd card and now using: sudo dd if=/dev/zero of=/dev/mmcblk1 bs=1M count=100 shoudl help?

Or I need making another changes in different place of code? Because now I am little confused.

KS

[Krzysztof Śmiałek]

Ok, for now I have flashed board with Debian 7.5 (BeagleBone Black - 2GB eMMC) 2014-05-14 

Than I remove card from BBB and install on the card: Debian 9.5 2018-08-30 4GB SD IoT

Flashing this distro probably will not be possible because of little space od eMMc. (I have tried it before)

Ond the SD card I need to change name of file to "uEnv.txt" to update the bootloader and after that I can use the newest distro. But what I need to do now to can use a PWM? If I use now: sudo dd if=/dev/zero of=/dev/mmcblk1 bs=1M count=100

The BBB will not get up. Need I make another changes in files on SD or emmc?

I am very newbie in BBB and now I am little confused :)

So tell me please step by step what should I do :)

Thanks!

The dd command is used to ERASE the eMMC u-Boot. Without u-Boot on the
eMMC, the bootstrap sequence tries to load u-Boot from an SD card. If you
don't have an SD card installed for this, the board will not boot.

The u-Boot in the 2GB image you are using to flash with is too old to
be used with newer OS variations (it expects the Linux kernel to load the
device tree, but new kernels expect u-Boot to load the device tree).

Your choices (to me) appear to be to either run with a three year old,
unsupported, OS that fits in the eMMC; or run with an eMMC that has no
u-Boot and needs to have an SD card holding a more recent OS/u-Boot; OR
figure out how to take a recent IoT image and REMOVE enough stuff from it
to let it fit into the 2GB eMMC, and then flash the eMMC using this
stripped down image with a modern u-Boot.*


* I don't know enough about the flashing process to know if it is done on
a "by file" basis, or is done "by block". If the former, getting the used
space of the SD card down to around 1.5-1.8GB might be sufficient; if it is
by blocks, you'd have to somehow compress the SD card free space and shrink
the partition...
Perhaps Mr. Nelson could chime in on this part of the mysterious BBB
flashing process?

So it's just rsync that copes files, so when it error's out, it really
just error's out from lack of space..

One option, for the 2GB eMMC that I've slightly played with but
haven't tested in a flashing situation... Btrfs with compression..

With BTFS with lzo, cut down the iot image from 3.3G to 1.6-ishG...
Well somewhere around there, it's been a few months..

[Krzysztof Śmiałek]

Ok, for me it is not important to flash emmc. I can use system from card. And I want use this method. So, what should I do step  by step? For this momet I have got old version on the emmc and ne we on sd card. If i remove card, BBB boot from emmc. If I insert card, BBB boot from sd card. But when I am using system form card there is problem with this PWM by adafruit in python. When I use this comand: sudo dd if=/dev/zero of=/dev/mmcblk1 bs=1M count=100 after rebooting BBB dont get up. All leds are off. With card, without don't matter. BBB is off.

Hi,

So what should I do now? First I tell you where am I at the moment, because I've made a lot of strange things and just today I came back to start point.

- I have got flashed emmc by this old image.

- I install the newest version of soft from site. Then I change name of file "BBB-uEnv.txt" to uEnv.txt because I found there infromation:

"##Rename as: uEnv.txt to override old bootloader in eMMC

##These are needed to be compliant with Debian 2014-05-14 u-boot."

Only after that i can boot from my sd card. But now there is still porblem with pwm from adafruit library.

I typed in promt after boot from card:

debian@beaglebone:~$ sudo fdisk -l
Disk /dev/mmcblk0: 14.5 GiB, 15552479232 bytes, 30375936 sectors

Disk /dev/mmcblk1boot1: 1 MiB, 1048576 bytes, 2048 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes


Disk /dev/mmcblk1boot0: 1 MiB, 1048576 bytes, 2048 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

So now if I type: "sudo dd if=/dev/zero of=/dev/mmcblk1 bs=1M count=10" I will delete all from my emmc and after that my BBB will not get up from SD.

So tell me please what should I do now? I have got clean version (without updates) in emmc and on sd card.

I'd erase the eMMC:

sudo dd if=/dev/zero of=/dev/mmcblk1 bs=1M count=100

Then utilize any image on the microSD..

Stick this image on a microSD card:

https://rcn-ee.net/rootfs/bb.org/testing/2018-09-23/stretch-lxqt-2gb/BBB-blank-debian-9.5-lxqt-2gb-armhf-2018-09-23-2gb.img.xz

using your thumb nail hold the boot button.

Insert power

After the 4 leds come on, lift thumb nail..

Should flash the eMMC in 5-10 minutes.
