Unfortunately, these tools do not shut down the USB controller before executing the downloaded code, and so the host PC does not "de-enumerate" the USB device. This option shuts down the USB controller when U-Boot boots to avoid leaving a stale USB device present. config SYS_MALLOC_F_LEN default 0x1800 source "arch/arm/mach-tegra/tegra20/Kconfig" source "arch/arm/mach-tegra/tegra30/Kconfig" source "arch/arm/mach-tegra/tegra114/Kconfig" source "arch/arm/mach-tegra/tegra124/Kconfig" source "arch/arm/mach-tegra/tegra210/Kconfig" source "arch/arm/mach-tegra/tegra186/Kconfig" endif
