I think it might be useful to leave USB gadget support in, since there are those who might prefer a USB console over the serial port. However if others disagree, I have this comment: If you are going to turn off the gadget, why not remove the USB driver too? > -tweaked blob load address to avoid image relocation (according to > default uImage load address); I don't think this does what you think it does! Unless I am horribly mistaken, the loadaddr address environment variable has nothing to do with relocation! It is the address typically used to store data when you do a fatload, tftp, bootp, etc. Steve > Signed-off-by: Sergiy Kibrik <sergiy.kib...@globallogic.com> > --- > include/configs/omap4_panda.h | 8 ++++---- > 1 files changed, 4 insertions(+), 4 deletions(-) > > diff --git a/include/configs/omap4_panda.h b/include/configs/omap4_panda.h > index 74defab..5aba424 100644 > --- a/include/configs/omap4_panda.h > +++ b/include/configs/omap4_panda.h > @@ -62,10 +62,10 @@ > > /* > * Size of malloc() pool > - * Total Size Environment - 256k > + * Total Size Environment - 2k > * Malloc - add 256k > */ > -#define CONFIG_ENV_SIZE (256 << 10) > +#define CONFIG_ENV_SIZE (256 << 4) > #define CONFIG_SYS_MALLOC_LEN (CONFIG_ENV_SIZE + (256 << 10)) > /* initial data */ > /* Vector Base */ > @@ -117,7 +117,7 @@ > > /* USB device configuration */ > #define CONFIG_USB_DEVICE 1 > -#define CONFIG_USB_TTY 1 > +#undef CONFIG_USB_TTY > #define CONFIG_SYS_CONSOLE_IS_IN_ENV 1 > > /* Flash */ > @@ -146,7 +146,7 @@ > #define CONFIG_ENV_OVERWRITE > > #define CONFIG_EXTRA_ENV_SETTINGS \ > - "loadaddr=0x82000000\0" \ > + "loadaddr=0x80007FC0\0" \ > "console=ttyS2,115200n8\0" \ > "usbtty=cdc_acm\0" \ > "vram=16M\0" \ > -- > 1.7.0.4 > > _______________________________________________ > U-Boot mailing list > U-Boot@lists.denx.de > http://lists.denx.de/mailman/listinfo/u-boot > _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
