Siemens boards are now using DFU in fullspeed only. For this CONFIG_USB_GADGET_DUALSPEED is undefined. Signed-off-by: Heiko Schocher <hs@denx.de> Cc: Tom Rini <trini@ti.com> Cc: Lukasz Majewski <l.majewski@samsung.com> Cc: Marek Vasut <marex@denx.de> Cc: Liu Bin <b-liu@ti.com> Cc: Lukas Stockmann <lukas.stockmann@siemens.com> --- On the siemens board this is needed because of a protection circuit. The device is 24V AC powered, if someone uses a non galvanically isolated transformer and misswires it, it could burn down the USB host. That's why we have a protection on the USB side which limits the speed to 12Mbit/sec. - changes for v2: - get rid of config option CONFIG_DFU_FULLSPEED as Bin Liu suggested. --- include/configs/siemens-am33x-common.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
