Hi,
the get_default_envs.sh script generates a text file
which represents the compiled in default environment.
It would be handy to specify the text file, to have a environment
image for production, different from default.
I think about:
Kconfig:
config U_BOOT_ENV_IMAGE
bool
...
if U_BOOT_ENV_IMAGE
config U_BOOT_ENV_IMAGE_SOURCE
string ""
help
Text file describing the environment. The file should have
lines of the form var=value, one per line. Blank lines and
lines starting with a # are ignored..
Leave empty to generate image from compiled-in env.
...
I am fine with U_BOOT_DEFAULT_ENV_IMAGE_SIZE and
U_BOOT_DEFAULT_ENV_IMAGE_REDUNDANT.
And in make file:
$(U_BOOT_MAKE_ENV) $(if $(call
remove_quotes,$(PTXCONF_U_BOOT_ENV_IMAGE_SOURCE)), \
cat "$(shell ptxd_get_alternative config/images
$(PTXCONF_U_BOOT_ENV_IMAGE_SOURCE) && echo "$$ptxd_reply" || ptxd_bailout
"could not find u-boot env file")", \
$(U_BOOT_DIR)/scripts/get_default_envs.sh) | \
mkenvimage -p 0x0 \
Not sure if config/images the the right place and layout should be better.
BTW ptxdist will search SYSROOT_HOST for mkenvimage, so there is no need to be
verbose.
Regards Denis
