OMAP5: Booting build output

OMAP5: Booting build output

[Ian M. Wisbon]

Hello,

I've completed a build for the OMAP5 uEVM using the meta-ti layer, and
was wondering whether there is any documentation for booting the
resulting output? Particular DIP switch settings, viable means of
booting - SD/USB/eMMC, particular formatting operations for SD, etc.

I am familiar with the documentation on OMAPpedia wrt OMAPBOOT, but I'm
not looking to boot/flash Android - and as you're building U-boot
MLO/img this doesn't seem applicable, but correct me if I am wrong. I
understand that the documentation may be limited/restricted at this
time, so if necessary I will contact the appropriate sources, or wait
until such time as documentation is released.

Regards,

Ian,

We are updating the base images to boot this more easily.  Until then you can boot from an SD card that has a FAT boot partition and the rootfs in an EXT partition.

You need to pass one of the device tree files from the deploy directory as well.  If you use the attached boot.scr (It is called boot.txt so please rename it) file in your FAT partition you can just rename the omap5-panda.dtb file to omap5-evm.dtb in the FAT partition and the boot should work on a uEVM.  These names are changing in the next kernel to omap5-uevm.dtb by default.

Sincerely,
Chase Maupin

Re: OMAP5: Booting build output

[Ian M. Wisbon]

Chase,

Thank you!

Does the SYSBOOT switch dictate whether the SD is used for booting? If
so, what is the correct setting? I've previously attempted to boot
using an SD card formatted as necessary for the OMAP4 Panda, but have
been unsuccessful - I assumed a similar FAT format would be required
for MLO/u-boot.img

Also - thank you for the boot script, as I just now saw the commit
changing the console from ttyO0 to ttyO2.

My sysboot switch is off on off on and I'm booting from SD.

You can use the same SD format at omap4.  Just replace the kerel and bootloader, add the boot.scr and dtb file.

Re: OMAP5: Booting build output

[Ian Wisbon]

Chase,

Thanks - I have mine set to the same:

off-on-off-on

and still no luck booting. I also tried the reverse just in case I was
backwards/upside-down; despite the same SD card booting an OMAP4 Panda,
and replacing with OMAP5 MLO and u-boot.img, I see nothing on the
console whatsoever. Not even a junk character implying an incorrect
baudrate, etc. The USBBOOT functionality seems to work, so I don't
believe the board to be non-functional.

I'll sit tight for a while and see what else is committed. Thanks for
your assistance!

Are you connected to ttyUSB0 or ttyUSB1?  For my board the serial is ttyUSB0.

Re: OMAP5: Booting build output

[Ian Wisbon]

Chase,

I've got a 4-port USB serial adapter connected to my host, so, it
enumerates as ttyUSB5 on my host.

I'm connecting to the micro-USB port labeled DEBUG USB, and the LED
indicating debug power is lit, screen /dev/ttyUSB5 115200

Applying power, LEDs D1 and D2 light blue, but otherwise, nothing
lights; I don't see a link come up either on the eth port.

In the dmesg output you should see two ttyUSB devices enumerated when the FTDI is detected.  The first is the serial console.  I'm not sure about your setup but if you have a 4 port serial adapter I would expect those are ttyUSB0 - ttyUSB3.  This would make the FTDI ttyUSB4.

The first thing we need is that you can see the serial console.  In some ways I wish this was like the beaglebone where you would see CCCCC when no SD card is loaded to know your serial connection was working :(

Ethernet won't work until later kernels.  I haven't tried the one Denys just updated to yet but ethernet is supposed to work there.

Re: OMAP5: Booting build output

[Ian Wisbon]

Chase,

For some reason, basic arithmetic and counting from zero escaped me
today.

You are of course, correct, as the 4 port enumerates ttyUSB0-3, and the
uEVM, then creates ttyUSB4 and ttyUSB5 - ttyUSB4 being the correct dev
entry. That's what I get for not looking at dmesg, and, counting. Thank
you sir. It does, in fact, load the bootloaders.

I appreciate your time, and, hopefully this will serve to help others -
sorry for the bother!

Cheers,

Ian

But with that we are hearing reports the DSS is broken... :(

Yes, there are still refinements and testing needed.  That is part of why the tags aren't in place yet.  I'll get a build out this weekend so the test team can start on monday
