I use bootloader like:
Toradex Bootloader 2.0 BETA 4 for Tegra Built Jan 4 2017 Press [SPACE] to enter Bootloader Menu BootLoader Configuration: C) Clear Flash Registry X) Enter CommandPrompt Mode D) Download image to RAM now F) Download image to FLASH now L) Launch existing flash resident image now
Enter your selection: x
** >set gpio **
gpio.bootconf (Boot GPIO settings. Do not remove default config. (Max 1536 chars)): '[gpio_168] altfn=-1 [gpio_169] altfn=-1 [gpio_170] altfn=-1 [gpio_171] altfn=-1 pull=down [gpio_172] altfn=-1 [gpio_173] altfn=-1 [gpio_174] altfn=-1 [gpio_175] altfn=-1 '
- I know I should keep existing string, but for my tests it should be irrelevent, yes? *
Next I try to change my real T20 GPIO (DIMM_97;L3;VI_D5) settings, forcing OUT-level 1:
set gpio.bootconf="[gpio_97] altfn=-1 outmode=std dir=out lvl=1 pull=up " saveconfig gpio
IMPORTANT: Here I had to type the string using “double-quotes”, while report above was ‘single-quoted’!)
Now, I boot WinCE7 and use the GPIOConfig tool to check state, but nothing has changed. (also checked pin voltage, nothing)
Is the string syntax correct? any other requirements to activate gpio.bootconf?
