======= Carioca ======= Carioca is a variation of Samba or, in the present case, of SAM-BA. SAM-BA is a full-blown in-system programmer developed and distributed by Atmel to support bootstrapping their various SAM microcontrollers. SAM-BA is proprietary, meaning that (most) of the source code is unavailable to SAM-BA users. Thus, if something breaks there, only Atmel can fix the problem. In contrast, Carioca is a minimal and open-source tool with similar goals as SAM-BA. It is minimal in the sense that it does not have any of the complex code required to initialize hardware components such as DRAM or to program flash memory. Instead Carioca provides just enough support to enable booting a primary bootloader and from there an operating system such as Linux. All flash programming etc. can then be done from within the target's operating system. Carioca has two modes: script mode and terminal-emulation mode. It starts out in script-mode where it executes zero or more scripts stored in files. There is also an interactive script mode where a user can type commands interactively in a terminal. Once the scripts are done, Carioca usually switches into terminal-emulation mode. In this mode, Carioca simply passes the serial traffic from the target's serial interface to the terminal Carioca was started in. This enables a user to observe the boot process of the target's operating system, to log in and to execute commands as needed. With these two modes, Carioca enables bootstraping a SAM microcontroller through a single serial interface (such as the Debug serial port), rather than the two ports typically required with SAM-BA (Debug serial port and USB serial interface). Carioca is written entirely in Python 3 and the scripting language has been influenced by another, now defunct Python project called Sam_I_Am (the two projects share no actual code, though, and their scripts are not compatible). Quick start ----------- 1. Install with:: pip install --user carioca (or use "pip3" if that's the version providing Python 3). 2. Connect a target board with a SAM microcontroller to your computer using either its Debug serial port or the USB serial port. On Linux, the former would typically show up as device **/dev/ttyUSB0**, the latter as **/dev/ttyACM0**. 3. If the target's serial port shows up as **/dev/ttyUSB0** on your computer and the target's serial port speed is **115,200 baud**, then start Carioca like this:: ~/.local/bin/carioca You can use option -p to specify a non-default serial port (such as "**-p /dev/ttyACM0**") and the -b option to specify a non-default baudrate (such as "**-b 57600**"). 4. Power up the target board. Assuming your target has not been setup for automatic booting yet, you should see a "**RomBOOT**" prompt. If so, continue. 5. Quit Carioca's terminal emulator by typing "**Ctrl-] quit**", followed by the **Enter** key. 6. Start Carioca's interactive script mode with:: ~/.local/bin/carioca - This will give you a "**carioca$**" prompt. You can type "**help**" to get a list of available commands. When executing the first command requiring interaction with the target, Carioca report's the target's SAM-BA Monitor version. For example:: carioca$ writeb 0x200000 42 will write the value 42 to memory location 0x200000 and respond with:: Connected to SAM-BA Monitor v1.1 Jul 31 2015 15:09:09 Typically, you'll want to send the primary bootstrap loader to the microcontroller's SRAM and then start execution. This could be achieved with:: carioca$ sendimg 0x200000 "at91bootstrap.bin" carioca$ go 0x200000 As soon as the "**go**" command is executed, Carioca will switch to terminal-emulation mode so you can observe the boot process and interact with the target as needed. 7. When you get tired if playing with the target system, type "**Ctrl-] quit**", followed by the **Enter** key to quit Carioca.
