Introduction:
|
||||
-------------
|
||||
The J721e 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
|
||||
- 2 x Dual cortex ARM Cortex-R5 subsystem
|
||||
- 2 x C66x Digital signal processor sub system
|
||||
- C71x Digital signal processor sub-system with MMA.

Boot Flow:
|
||||
----------
|
||||
Boot flow is similar to that of AM65x SoC and extending it with remoteproc
|
||||
support. Below is the pictorial representation of boot flow:

OSPI:
|

-----
|

ROM supports booting from OSPI from offset 0x0.
|
||||
|
||||
Flashing images to OSPI:
|
||||
|
||||
Below commands can be used to download tiboot3.bin, tispl.bin, u-boot.img,
|
||||
and sysfw.itb over tftp and then flash those to OSPI at their respective
|
||||
addresses.
|
||||
|
||||
=> sf probe
|
||||
=> tftp ${loadaddr} tiboot3.bin
|
||||
=> sf update $loadaddr 0x0 $filesize
|
||||
=> tftp ${loadaddr} tispl.bin
|
||||
=> sf update $loadaddr 0x80000 $filesize
|
||||
=> tftp ${loadaddr} u-boot.img
|
||||
=> sf update $loadaddr 0x280000 $filesize
|
||||
=> tftp ${loadaddr} sysfw.itb
|
||||
=> sf update $loadaddr 0x6C0000 $filesize
|
||||
|
||||

OSPI:
|
||||
-----
|
||||
ROM supports booting from OSPI from offset 0x0.
|
||||
|
||||
Flashing images to OSPI:
|
||||
|
||||
Below commands can be used to download tiboot3.bin, tispl.bin, u-boot.img,
|
||||
and sysfw.itb over tftp and then flash those to OSPI at their respective
|
||||
addresses.
|
||||
|
||||
.. code-block:: text
|
||||
|
||||
=> sf probe
|
||||
=> tftp ${loadaddr} tiboot3.bin
|
||||
=> sf update $loadaddr 0x0 $filesize
|
||||
=> tftp ${loadaddr} tispl.bin
|
||||
=> sf update $loadaddr 0x80000 $filesize
|
||||
=> tftp ${loadaddr} u-boot.img
|
||||
=> sf update $loadaddr 0x280000 $filesize
|
||||
=> tftp ${loadaddr} sysfw.itb
|
||||
=> sf update $loadaddr 0x6C0000 $filesize
|
