can you compare the sizes of .52 and .53.1 so we know how much it will be
for an armv5 target :
0.53.1 : 228112
0.53.1 + DROPBEAR_SMALL_CODE : 178960
0.52 : 183008
Looks like DROPBEAR_SMALL_CODE is still worth having then. Why was it
disabled?
the changelog doesn't say it but the comment in option.h says :
/* Set this if you want to use the DROPBEAR_SMALL_CODE option. This can save
several kB in binary size, however will make the symmetrical ciphers (AES, DES
etc) slower (perhaps by 50%). Recommended for most small systems. */
so maybe they prefered to get performance by default instead of saving 50kB.
We can keep this option by adding this to the recipe :
+do_configure_prepend() {
+ echo "#define DROPBEAR_SMALL_CODE" >>${S}/options.h
+}
+
