devo7e with empty Main menu

Help!

I am new in Deviation and live in Windows world.

I just managed setup my environment in WIN 8. I have two problems.

1. I can build devo7e smoothly with the following command:

make zip TARGET=devo7e

With the generated dfu file, the radio can be turned on, the main screen display is ok. But when pressing the the Ent button, the Main menu is empty. I copied the protocol folder in the zip file over the older one.

Tried both the latest default source and V4.0.1 tag. They are the same. However, the official pre-build dfu file works fine.

Something missing or need extra configuration to build 7E?

2. When do "make TARGET=emu_devo7e WINDOWS=1"
Get error
E:/MinGw/msys/1.0/include/sys/config.h:109:5: error: "INT_MAX" is not defined [-Werror=undef]
#if INT_MAX == 32767
...

Thank you in advance!

Your flashdrive content has to match the version of the DFU you are flashing. Just the protocol folder alone will not do, as the manual says. Copy the whole filesystem over.

Thank you Arakon.

After I copied src/filesystem/devo10/media/config.ini to the target USB drive, I got the menu dispalyed!

By the way, how to generate the particular images for 7E USB file system? The zip file has only "protocol" folder. The folder "filesystem" under src seems not having the same structure as in the USB drive. Should I manually pick up folders from the src/filesystem?

After a few week play, I understand the environment better.

Unlike may other ARM systems, which store programs in ROM/flash, and load them into RAM to run, STM32 has special features that can run directly from Flash with the same speed of RAM.

However, because of the space limitation of 7E (128KB), the protocol modules are compiled as bin (mod) files and stored in the 2MB USB accessible flash drive. When we change a protocol or load a new model, the selected mod file is loaded into RAM to be used.

The addresses of variables are changing in every compiles of different code. Beside loading "src/deo7e.dfu" into the flash with DfuSe tool, we also have to copy the folder "src/objs/devo7e/protocol" to the USB flash driver for every build.

Without match dfu and protocol folder, the radio crashes.

Wish the info can help for newbies.
