Other Parts Discussed in Thread: CONTROLSUITE
Tool/software: Code Composer Studio
Hello,
I am trying serial flash programming of C2000 LaunchPadXL 28027F through a transceiver (USB to TTL FT232RL) following a Serial Flash Programming of C2000™ Microcontrollers application report (www.ti.com/.../sprabv4b.pdf).
Following the application report, I set the GPIO pins as visible in the table below. This should put it into SCI Boot mode. The link transceiver was connected correctly (RX to TX and GND to GND)
| GPIO37 | 0 |
| GPIO34 | 1 |
| TRST | 0 |
As the application report suggests I used both the application and kernel projects from Control suite building it in code composer studio as .out file and then converting it using hex2000 to .txt file. After getting all this I used serial flash programmer to get it on to the microcontroller.
Command used:
C:\ti\controlSUITE\device_support\~Utilities\serial_flash_programmer>serial_flash_programmer -d f2802x -k f28027_flash_kernel.txt -a application.txt -p COM3 -b 38400
This is what I have recieved:

Downloading application.txt to device...
This has been going on for 1,5 hours with both the transceiver and the board looking like nothing is happening. I have read a forum discussion where a guy was waiting for an hour with 9600 boud but it was on a different board and I am already using 38400.
The application report says: ". The ROM cannot access RAM protected by the Code Security Module (CSM). Therefore, the device needs to be unlocked, or the load must be to unsecure RAM." What I am not 100% sure I understand. Can it be somehow connected to my problem?
Does any one have any suggestions what might be going on?
