1.d. Use CPLD Configurator
- H3_M3_StarterKit_Configurator.exe is a Windows tool shipped by Renesas, hence readily available, which allows to modify the MD pins, to conveniently switch between QSPI/Hyperflash/SCIF boot mode from a GUI
- Most of the advantages pointed out above
- ULCB-only solution (i.e. does not apply to Salvator-X)
- Requires a Windows host
Where can I obtain this and are there sources / documentation available?
I am able to find below related package freely available: https://elinux.org/File:H3_StarterKit_CPLD_Update_20190408.zip
Unfortunately, it doesn't include H3_M3_StarterKit_Configurator.exe. The user who uploaded the file is https://elinux.org/User:RenesasJa. Are you aware of any messaging/commenting feature on elinux.org? If not, I hope Michael (CC-ed) can answer your question. Hopefully he sees this message. If not, I can forward your question to him via mantis.
It would be also interesting to obtain the CPLD sources and be able to synthesise custom CPLD bitstreams for automated testing.
Is my understanding correct that these "CPLD bitstreams" (once known) could be implemented in U-Boot's board/renesas/ulcb/cpld.c?
