Hi,

I included a patch that adds support for CS boot mode recognition on OMAP1610 Innovator and H2 boards. Currently you have to build U-Boot either for CS0 or CS3 boot mode. The patch adds new make targets for binaries that will check the boot mode and set flash address accordingly. Also some board specific init steps are skipped when booting from RAM. The new targets are: omap1610h2_cs_autoboot_config omap1610inn_cs_autoboot_config

Please explain where the name "autoboot" comes from.

Best regards,

Please explain where the name "autoboot" comes from. From memory, I believe this name is used by the documentation from TI for

the DIP switch that swaps the boot mode from flash=CS3 to flash=CS0. It's not a very good name, and on other boards that do the same it is also referred to as "fast boot" and "arm boot" none of which are terribly descriptive or useful...

Best Wishes,

Thanks, added - except for the part which modifies common/env_flash.c

Here, instead of simply initializing the relevant variables at compile time, you added code to do this at run time. I don't think this is a good idea. Please explain why you are doing this, and which problem you attempt to fix.

Best regards,
