Re: [beagleboard] PocketBeagle SD Card Extra Storage

[jackfhunt1015]

Hi Karishma,

Since Jason and Robert helped me out so much there shouldn't be too much to 
do.
Beagle bone green and pocket beagle use the same debian version. 
So I'd assume you just have to load the latest version and then edit the 
uEnv.txt like I 
did. https://github.com/beagleboard/pocketbeagle/wiki/Click-boards™

If that doesn't work for you I'd suggest posting a new question because I 
am by no means an expert.

Regards,
Jack

 I found it in the 4.9 driver and made an attempt to build it natively 
 as a module and give it a try:

 https://gist.github.com/jadonk/53ae22d550021bf32a299acbd7b546aa 

 I optimized the loading time for the git clone with a shallow checkout. 
 The build happens pretty fast. It didn't load for me at first. I was able 
 to load it, by doing a depmod and modprobe manually, but it never reports 
 anything beyond:

 mmc_spi spi2.1: SD/MMC host mmc3, no WP, no poweroff

 So, got any ideas? How should I specify the interrupts?

 sudo apt-get update
 sudo apt-get install linux-headers-`uname -r`
 cd
 mkdir linux
 cd linux/
 git init
 git config core.sparsecheckout true
 git remote add origin https://github.com/beagleboard/linux
 echo drivers/mmc/host > .git/info/sparse-checkout  
  
 git fetch origin/4.9 --depth 1
 git checkout 4.9
 cd drivers/mmc/host
 CONFIG_MMC_SPI=m make -C /lib/modules/`uname -r`/build M=$PWD
 sudo make -C /lib/modules/`uname -r`/build M=$PWD 
 INSTALL_MOD_DIR=kernel/drivers/mmc/host modules_install

 cd /lib/modules/`uname -r`
 sudo depmod -a

Hi 
I am trying the same thing with Beagle bone green board. 
Can u help me in this as you mentioned that it worked for you.
Thanks

 Oh, that's easy, prove it can work, and provide a pull request here
 for both spix positions:

 https://github.com/beagleboard/bb.org-overlays/

 Then update the wiki.

 Just because I haven't purchased that click doesn't mean it 'will not' 
 work.. ;)

 There's a new driver in v4.14.x? and a device tree node; "mmc-slot"
 CONFIG_MMC_SPI

Re: [beagleboard] PocketBeagle SD Card Extra Storage

[jackfhunt1015]

I've gotten the sd card overlay working, thank you for the help! Now I'm 
trying to read and write a file to it in python but am struggling finding 
the directory that it is in. Any idea on how to locate this path?

Re: [beagleboard] PocketBeagle SD Card Extra Storage

[Jason Kridner]

With Robert’s integration, there’s no longer a need to debug my steps. Use 
/opt/scripts/tools/update_kernel.sh to get the latest 4.9 kernel. Googling for 
that script name should get sufficient instructions. Once on that kernel, do 
the /boot/uEnv.txt edit as indicated.

Re: [beagleboard] PocketBeagle SD Card Extra Storage

[jackgig2014]

Im having trouble executing this command


git fetch origin/4.9 --depth 1


Im consistently getting the error


fatal: 'origin/4.9' does not appear to be a git repository
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.4


How can I get the correct access rights to run the 4.9 kernel?

Re: [beagleboard] PocketBeagle SD Card Extra Storage

[Robert Nelson]

Okay i got Jason's overlay working:

CD isn't working, looks more like a driver problem:

I found it in the 4.9 driver and made an attempt to build it natively as a
module and give it a try:

https://gist.github.com/jadonk/53ae22d550021bf32a299acbd7b546aa

I optimized the loading time for the git clone with a shallow checkout. The
build happens pretty fast. It didn't load for me at first. I was able to
load it, by doing a depmod and modprobe manually, but it never reports
anything beyond:

mmc_spi spi2.1: SD/MMC host mmc3, no WP, no poweroff

So, got any ideas? How should I specify the interrupts?

sudo apt-get update
sudo apt-get install linux-headers-`uname -r`
cd
mkdir linux
cd linux/
git init
git config core.sparsecheckout true
git remote add origin https://github.com/beagleboard/linux
echo drivers/mmc/host > .git/info/sparse-checkout
git fetch origin/4.9 --depth 1
git checkout 4.9
cd drivers/mmc/host
CONFIG_MMC_SPI=m make -C /lib/modules/`uname -r`/build M=$PWD
sudo make -C /lib/modules/`uname -r`/build M=$PWD
INSTALL_MOD_DIR=kernel/drivers/mmc/host modules_install

cd /lib/modules/`uname -r`
sudo depmod -a

Oh, that's easy, prove it can work, and provide a pull request here
for both spix positions:

https://github.com/beagleboard/bb.org-overlays/

Then update the wiki.

Just because I haven't purchased that click doesn't mean it 'will not' work.. ;)

There's a new driver in v4.14.x? and a device tree node; "mmc-slot"
CONFIG_MMC_SPI

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/mmc/mmc-spi-slot.txt
