Hey Jason,

Finally had time to get back to this.

I bought your book BeagleBone Cookbook, 

downloaded, and flashed the latest debian image from beaglebone.org:

AM3358 Debian 10.3 2020-04-06 4GB SD IoT 

onto an sdcard, got it to boot with the BOOT button, and tried to install pruspeak,

and ran into this:

root@beaglebone:~/pruspeak# sh install.sh

if [ ! -d "/lib/modules/4.19.94-ti-r42/build" ]; then apt-get install linux-headers-4.19.94-ti-r42; fi

make -C /lib/modules/4.19.94-ti-r42/build M=/root/pruspeak/src/driver modules

make[1]: Entering directory '/usr/src/linux-headers-4.19.94-ti-r42'

  CC [M]  /root/pruspeak/src/driver/pru_speak.o

/root/pruspeak/src/driver/pru_speak.c:26:10: fatal error: plat/mailbox.h: No such file or directory

 #include <plat/mailbox.h>

          ^~~~~~~~~~~~~~~~

compilation terminated.

I don’t see plat/mailbox.h in /usr/src/linux-headers-4.19.94-ti-r42:

Only see:

./include/config/mailbox.h

./include/dt-bindings/mailbox/tegra186-hsp.h

./include/linux/mailbox_controller.h

./include/linux/omap-mailbox.h

./include/linux/mailbox_client.h

./include/linux/mailbox/brcm-message.h

./include/linux/mailbox/mtk-cmdq-mailbox.h

I tried substituting linux/omap-mailbox.h, and it spewed a bunch of errors...

Not sure what I am missing.

Happy to post this on a message board, and when I tried to do a search at:

http://beagleboard.org/search

I got 502 Bad Gateway  nginx/1.14.0 (Ubuntu) as an error message.

Hope you can help point me in the right direction.

Thanks so much in any case,

Karl

I rather like working with the PRU using the Cloud9 IDE setup and the makefile I have it configured with.

I hope this message finds you doing well,
and thanks for any advice you can lend here.

I really prefer to answer with beagl...@googlegroups.com in copy.

 

All the best,

Karl

Dear discussion group,

Am I supposed to see a response to this email on a board somwhere?

Or will I see it as an email response.

Thanks so much,

Karl
