Re: [U-Boot] Disable tftp and access

Hi!

I haven't tested this approach, but you can define the following variables in your board config (see include/configs/mimc200.h for example): #define CONFIG_SILENT_CONSOLE /* enable silent startup */ #define CONFIG_DISABLE_CONSOLE /* disable console */ #define CONFIG_SYS_DEVICE_NULLDEV /* include nulldev device */

Then you can set "stdin=nulldev\0" in your environment. I hope it helps.

I should also mention that if you are going to sell devices and want to completely disable access to the firmware/software, then you should also somehow disable debug ports (such as JTAG).
