Only partial file is saved with download_apps on BCM943907AEVAL1F

[Anonymous]

When building snip.stdio using WICED 5.2 download apps and a 909740 byte file on the BCM943907AEVAL1F only 24 sectors were allocated for the file. Also a resources file was saved when the only thing I specified was APP0.

Here is the output from the make:

Here is the makefile I used:

NAME := App_stdio

$(NAME)_SOURCES := stdio.c

APP0 := apps/snip/stdio/b445586f3985f4cab7f3bef20d74c549.elf

I also tried the rebranded platform to see if that would work and got the same result:

Because the BCM943907AEVAL1F has no internal flash, the bootloader uses APP0 as the main system image that is initially loaded. Apparently APP0 is reserved for this, so I have to use some other image like APP1 if I want to save a file to external flash. This is what I got when I used APP1 instead:

It works, it just doesn't work with APP0.
