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). ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

Re: [U-Boot] Disable tftp and access
Thanks for answer, according to http://www.denx.de/wiki/view/DULG/UBootEnvVariables if I set bootdelay=0, then will not be possible to tftp image by dhcp or by push? I can't find information about possible options for stdin.

[U-Boot] Disable tftp and access
Hello, I want to disable uboot tftp on my device and if uboot allow some login/access(eg. by console) then disable it too. My aim is to lock uboot except booting image(OS), I want manage it only from OS(changing env variables only from OS) I want to ask what env variables I should change to disable tftp functions and access? Thanks, Kubco ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
