J7200 Platforms
===============
Introduction:
-------------
The J7200 family of SoCs are part of K3 Multicore SoC architecture platform
targeting automotive applications. They are designed as a low power, high
performance and highly integrated device architecture, adding significant
enhancement on processing power, graphics capability, video and imaging
processing, virtualization and coherent memory support.
The device is partitioned into three functional domains, each containing
specific processing cores and peripherals:
1. Wake-up (WKUP) domain:
* Device Management and Security Controller (DMSC)
2. Microcontroller (MCU) domain:
* Dual Core ARM Cortex-R5F processor
3. MAIN domain:
* Dual core 64-bit ARM Cortex-A72
More info can be found in TRM: https://www.ti.com/lit/pdf/spruiu1

Switch Setting for Boot Mode
----------------------------
Boot Mode pins provide means to select the boot mode and options before the
device is powered up. After every POR, they are the main source to populate
the Boot Parameter Tables.
The following table shows some common boot modes used on J7200 platform. More
details can be found in the Technical Reference Manual:
https://www.ti.com/lit/pdf/spruiu1 under the `Boot Mode Pins` section.
*Boot Modes*
============ ============= =============
Switch Label SW9: 12345678 SW8: 12345678
============ ============= =============
SD 00000000 10000010
EMMC 01000000 10000000
OSPI 01000000 00000110
UART 01110000 00000000
USB DFU 00100000 10000000
============ ============= =============
For SW8 and SW9, the switch state in the "ON" position = 1.
eMMC:
-----
ROM supports booting from eMMC raw read or UDA FS mode.
Below is memory layout in case of booting from
boot 0/1 partition in raw mode.
Current allocated size for tiboot3 size is 1MB, tispl is 2MB.
Size of u-boot.img is taken 4MB for refernece,
But this is subject to change depending upon atf, optee size
.. code-block:: console
boot0/1 partition (8 MB) user partition
0x0+----------------------------------+ 0x0+------------------------+
| tiboot3.bin (1 MB) | | |
0x800+----------------------------------+ | |
| tispl.bin (2 MB) | | |
0x1800+----------------------------------+ | |
| u-boot.img (4MB) | | |
0x3800+----------------------------------+ | |
| | | |
0x3900+ environment | | |
| | | |
0x3A00+----------------------------------+ +-------------------------+
In case of UDA FS mode booting, following is layout.
All boot images tiboot3.bin, tispl and u-boot should be written to
fat formatted UDA FS as file.
.. code-block:: console
boot0/1 partition (8 MB) user partition
0x0+---------------------------------+ 0x0+-------------------------+
| | | tiboot3.bin* |
0x800+----------------------------------+ | |
| | | tispl.bin |
0x1800+----------------------------------+ | |

0x3800+----------------------------------+ | |
| | | |
0x3900+ | | environment |
| | | |
0x3A00+----------------------------------+ +-------------------------+
In case of booting from eMMC, write above images into raw or UDA FS.
and set mmc partconf accordingly.
