IBex AST2700
|
||||
============
|
||||
|
||||
AST2700 integrates an IBex RISC-V 32-bits CPU as the boot MCU to execute the
|
||||
first stage bootlaoder, namely SPL.
|
||||
|
||||
Build
|
||||
-----
|
||||
|
||||
1. Prepare the toolchains and make sure the $PATH to toolchains is correct.
|
||||
2. Use `make ibex-ast2700_defconfig` in u-boot root to build the image
|
||||
|
||||
Running U-Boot SPL
|
||||
------------------
|
||||
|
||||
The U-Boot SPL will boot in M mode and load the FIT image which includes
|
||||
the 2nd stage bootloaders executed by the main processor Cortex-A35.
|
||||
|
||||
|
||||
Burn U-Boot to SPI Flash
|
||||
------------------------
|
||||
|
||||
Use SPI flash programmer (e.g. SF100) to program the u-book-spl.bin with the
|
||||
offset 0x80 bytes to the SPI flash beginning.
