Merge patch series "board: beagle: beagley-ai: Cleanups and stdboot"
Nishanth Menon <nm@ti.com> says:
Just happened to get a BeagleY-AI at desk and happened to test master
branch (7dd49a9264 drivers: scsi: Add 'erase' support), noticed a few
issues which were rather easy to solve.. so, here we go:

AM67A Beagleboard.org BeagleY-AI
|
||||
================================
|
||||
|
||||
Introduction:
|
||||
-------------
|
||||
|
||||
BeagleBoard.org BeagleY-AI is an easy to use, affordable open source
|
||||
hardware single board computer based on the Texas Instruments AM67A,
|
||||
which features a quad-core 64-bit Arm CPU subsystem, 2 general-purpose
|
||||
digital-signal-processors (DSP) and matrix-multiply-accelerators (MMA),
|
||||
GPU, vision and deep learning accelerators, and multiple Arm Cortex-R5
|
||||
cores for low-power, low-latency GPIO control.
|
||||
|
||||

Boot Flow:
|
||||
----------
|
||||
Below is the pictorial representation of boot flow:

:alt: Boot flow diagram
|
||||
|
||||
- On this platform, 'TI Foundational Security' (TIFS) functions as the
|
||||
security enclave master while 'Device Manager' (DM), also known as the
|
||||
'TISCI server' in "TI terminology", offers all the essential services.
|
||||
The A53 or R5F (Aux core) sends requests to TIFS/DM to accomplish these
|
||||
services, as illustrated in the diagram above.

-------------
|
||||
Copy these images to an SD card and boot:
|
||||
|
||||
* tiboot3-j722s-hs-fs-evm.bin from Cortex-R5 build as tiboot3.bin.
|
||||
* tispl.bin and u-boot.img from Cortex-A build.
|
||||
|
||||
Image formats
|
||||
-------------
|
||||
|
||||
- tiboot3.bin
|
||||
|
||||
.. image:: ../ti/img/multi_cert_tiboot3.bin.svg
|
||||
:alt: tiboot3.bin image format
|
||||
|
||||
- tispl.bin
|
||||
|

.. image:: ../ti/img/tifsstub_dm_tispl.bin.svg
|

:alt: tispl.bin image format

Additional hardware for U-Boot development
|
||||
------------------------------------------
|
||||
|
||||
* Serial Console is critical for U-Boot development on BeagleY-AI. See
|
||||
`BeagleY-AI serial console documentation
|
||||
<https://docs.beagleboard.org/boards/beagley/ai/02-quick-start.html#beagley-ai-headless>`_.
|
||||
* The only onboard storage option is uSD.
|
||||
* (optionally) JTAG is useful when working with very early stages of boot.
|
||||
|
||||
Flash to uSD card or how to deal with "bricked" Board
|
||||
-----------------------------------------------------
|
||||
|
||||
The only storage option on the platform is uSD card. However, if you
|
||||
choose to hand format your own bootable uSD card, be aware that it can
|
||||
be difficult. The following information may be helpful, but remember
|
||||
that it is only sometimes reliable, and partition options can cause
|
||||
issues. These can potentially help:
|
||||
|
||||
* https://git.ti.com/cgit/arago-project/tisdk-setup-scripts/tree/create-sdcard.sh
|
||||
* https://elinux.org/Beagleboard:Expanding_File_System_Partition_On_A_microSD
|
||||
* Or manually as follows (may not take into distro needs such as EFI or swap):
|
||||
|
||||
.. prompt:: bash #
|
||||
|
||||
# Create image with partition table
|
||||
parted --script <SD CARD DEVICE> \
|
||||
mklabel msdos \
|
||||
mkpart primary fat16 4MiB 20MiB \
|
||||
mkpart primary ext4 20MiB 100% \
|
||||
set 1 boot on \
|
||||
set 1 bls_boot off \
|
||||
set 1 lba on
|
||||
# Create boot partition
|
||||
mkfs.vfat <SD CARD DEVICE>1
|
||||
# Create root partition
|
||||
mkfs.ext4 <SD CARD DEVICE>2
|
||||
|
||||
The simplest option is to start with a standard distribution
|
||||
image like those in `BeagleBoard.org Distros Page
|
||||
<https://www.beagleboard.org/distros>`_ and download a disk image for
|
||||
BeagleY-AI. Pick a 16GB+ uSD card to be on the safer side.
|
||||
|
||||
With an SD/MMC Card reader and `Balena Etcher
|
||||
<https://etcher.balena.io/>`_, having a functional setup in minutes is
|
||||
a trivial matter, and it works on almost all Host Operating Systems.
|
||||
Yes Windows users, Windows Subsystem for Linux(WSL) based development
|
||||
with U-Boot and update uSD card is practical.
|
||||
|
||||
Updating U-Boot is a matter of copying the tiboot3.bin, tispl.bin and
|
||||
u-boot.img to the "BOOT" partition of the uSD card. Remember to sync
|
||||
and unmount (or Eject - depending on the Operating System) the uSD
|
||||
card prior to physically removing from SD card reader.
|
||||
|
||||
.. note::
|
||||
Great news! If the board has not been damaged physically, there's no
|
||||
need to worry about it being "bricked" on this platform. You only have
|
||||
to flash an uSD card, plug it in. This means that even if you make a
|
||||
mistake, you can quickly fix it and rest easy.
|
||||
|
||||
If you are frequently working with uSD cards, you might find the
|
||||
following useful:
|
||||
|
||||
* `USB-SD-Mux <https://www.linux-automation.com/en/products/usb-sd-mux.html>`_
|
||||

If the "red" power LED is not glowing, the system power supply is not
|

functional. Please refer to `BeagleY-AI documentation
