Creating the HSS payload - Microchip boot-flow
|
|
''''''''''''''''''''''''''''''''''''''''''''''
|
|
|
|
1. You will be creating a payload from `u-boot-dtb.bin`.
|
|
Copy this file to the HSS/tools/hss-payload-generator/test directory.
|
|
2. Go to hss-payload-generator source directory.
|
|
|
|
.. code-block:: none
|
|
|
|
cd hart-software-services/tools/hss-payload-generator
|
|
|
|
3. Edit test/uboot.yaml file for hart entry points and correct name of the binary file.
|
|
|
|
hart-entry-points: {u54_1: '0x80200000', u54_2: '0x80200000', u54_3: '0x80200000', u54_4: '0x80200000'}
|
|
|
|
payloads:
|
|
test/u-boot-dtb.bin: {exec-addr: '0x80200000', owner-hart: u54_1, secondary-hart: u54_2, secondary-hart: u54_3, secondary-hart: u54_4, priv-mode: prv_s}
|
|
|
|
4. Generate payload
|
|
|
|
.. code-block:: none
|
|
|
|
./hss-payload-generator -c test/uboot.yaml payload.bin
|
|
|
|
Once the payload binary is generated, it should be copied to the eMMC.
|
|
|
|
Please refer to HSS documenation to build the HSS firmware for payload.
