CC3235MODASF: Minimal flashing user program, preserving SimpleLink etc.

Malcolm Windham

Part Number: CC3235MODASF
Other Parts Discussed in Thread: UNIFLASH

I'm ready to test project in real world, but I would want toa avoid flashing over anything unnecessarily. Years ago, I seem to remeber on could load a user program in a specific location in the file system and it would be started after boot. Also, there was a thread about saving user configuration CC3235MODASF: How can I re-flash the MCU image preserviing WiFi profiles - Wi-Fi forum - Wi-Fi - TI E2E support forums that mad me think that ideally I would like to use the user configuration in connecting to network rather than hard coding in platform.c.. Is that possible?

MCU+Image:

gmake: *** [build-688872641] Error 1
gmake: Target 'all' not remade because of errors.

Is this because of my Windows username having a space in it? Debug works.

yes. Check the OTA example that updates specific files and not full flash content (since version 6.10 OTA is demonstrated through the MQTT_Client example).

The OTA_IF module (available as part of the MQTT_Client example) supports a mode called "internal update" (look for INTERNAL_UPDATE_SUPPORT) which allow to perform an update from a an OTA tar file located in the file system. It also support update from a cloud server (HTTP-GET) or update using mobile device (HTTP-PUT).

I am confused because I thought that MCU+Image meant the compile for flashing. I tried the uninstall ccs, add user with no spaces in account with admin, reinstall ccs, and got same error on compile for MCU+Image. What should I do for standalone test?

The error is probably because either the device is not connected or the UART port is busy.

For creating the programming image (after the debugger image is ready) as is done in MCU+Image, the CCS needs to read connected-device information.

try to update the syscfg version(in the project's Properties -> General -> Products) to 1.15 or later.

When I copied project, I had a "i2ctmp.cfg" excluded from build in previous debug project, but when copied, it was included. Now I'll look at OTA example.

When I compile MCU+Image, is the program loaded for execution on power cycle, or is there more to do?

If you use Uniflash or the Flash button (of CCS) - then you are writing the image to the serial flash and this will stay after power cycle.

If you download the code through the debugger - the code gets loaded to the internal XiP flash an after power cycle it will be overwritten by the external flash content.
