Registro de problemas en el uso de tarjetas Tiva¶
Log de errores en tarjetas Tiva¶
Registro de errores encontrados en las tarjetas Tiva C Series TM4C1294 en sus dos modelos:
- Connected LaunchPad
- Crypto Connected LaunchPad
Antes de agregar un nuevo error, verificar que la tarjeta no este listada, si ya esta listada agragar "Problema2:", "Solución2:", etc.
Modelo: Normal
MAC: 00:1A:B6:03:18:B9
Problema: Datos en EEPROM no se escribian.
Solución: Flasheo.
Equipo: Ninguno
Modelo: Crypto
MAC: :::::
Problema: colgado LCD (mientras estaba activo).
Solución: cambio de resistencias pull-ups 10K a 3.9K.
Equipo: CR con CGS (usado en JASMET).
Modelo: ?
MAC: :::::
Problema: colgado cada 90 minutos de ehternet, LCD no mostraba nada.
Solución: Cambio de Firmware arreglo la interfaz Ethernet y I2C (LCD). Shield para la Tiva ya tenia pull-up de 4K.
Equipo: CR Operaciones
Modelo: Crypto
MAC: 08:00:28:5A:8D:43
Problema: Ethernet dejo de funcionar.
Solución: Flasheo.
Equipo: Ninguno
Modelo: Crypto
MAC: 08:00:28:5A:85:D9...
Problema: Ethernet dejo de funcionar.
Solución: ??
Equipo: Ninguno
MISC¶
Problemas varios surguidos en la configuración de las tarjetas.
Problema: Librería I2C no funciona correctamente
Solución: Modificación de librería. La nueva librería se encuentra en .....
Poblema: se grabó un WTD muy corto y sin delay al inicio del programo, lo que mantenía al programa en constante reinicio en la función "setup" (Energia).
Solución: Flasheo.

Programming Guide¶
Alorium Sno¶
Steps¶
- Solder JTAG and power pins
- Install Quartus Prime Lite Edition
- Install the driver for the USB Blaster
- Control Panel > Device Manager
- Search for USB-Blaster
- Update Driver > Browse > \intelFPGA_lite\18.1\quartus\drivers
- With Quartus Prime Lite Edition software generate programming file [Assembler]
- Open Quartus Prime Lite Edition
- Go to Tools > Programmer
- Make sure that "USB-Blaster [USB-0]" is selected in Hardware Setup, otherwise click Hardware Setup and in "Currently selected hardware:" select it. Close
- Check the correct FPGA by clicking "Auto Detec" and select 10M16SA
- Click "Add File" and go to the project folder and search and open the programming file, either xxx.sof (lose at powerdown) or xxx.pof
- project_name/output_files/xxx.pof
- Select file and delete it
- Check the two boxes "Program/Configure" and "Verify" of the main file
- Program the FPGA by clicking "Start"
Notes¶
- *all steps were done using Windows 7
- When using on-chip memory IP cores change configuration mode to "Single Uncompresed Image with Memory Initialization" inside Device>Device and Pin Options...>Configuration mode
Alorium XLR8¶
Steps¶
- Solder JTAG pins
- Install Quartus Prime Lite Edition
- Install the driver for the USB Blaster
- Control Panel > Device Manager
- Search for USB-Blaster
- Update Driver > Browse > \intelFPGA_lite\18.1\quartus\drivers
- With Quartus Prime Lite Edition software generate programming file [Assembler]
- Open Quartus Prime Lite Edition
- Go to Tools > Programmer
- Make sure that "USB-Blaster [USB-0]" is selected in Hardware Setup, otherwise click Hardware Setup and in "Currently selected hardware:" select it. Close
- Check the correct FPGA by clicking "Auto Detec" and select 10M08SA
- Click "Add File" and go to the project folder and search and open the programming file, either xxx.sof (lose at powerdown) or xxx.pof
- project_name/output_files/xxx.pof
- Select file and delete it
- Check the two boxes "Program/Configure" and "Verify" of the main file
- Program the FPGA by clicking "Start"
Notes¶
- *all steps were done using Windows 7
- Notch of the USB Blaster's connector should face the inside of the board.
- For the use A0-5 pins there is 2 options: analog or digital, both connected to different pins on the FPGA. When used as digital, user has to enable this pins (buffer 3.3V-5V) through 6 pins also connected to the FPGA (see schematic).
- RST pin is active low.
- When using on-chip memory IP cores change configuration mode to "Single Uncompresed Image with Memory Initialization" inside Device>Device and Pin Options...>Configuration mode
Papilio Pro¶
Steps¶
- Install ISE Design Suite
- With ISE Design Suite software generate programming file [Generate Programming file]
- Download the file "Papilio-Loader-2.8-Setup.exe" (1) and install it
- Go to the project folder and search for the programming file xxx.bit
- Double click and wait for the Papilio Loader to open
- File > Preferences > User Mode > Expert
- In "Target board" field select "Papilio One or Papilio Pro"
- Make sure the "Target .bit file" loaded the correct file
- Do not touch the other fields and in the "Operations" box check "Erase", "Write to" and "Verify"
- In the drop-down menu select either "FPGA" (lose at powerdown) or "SPI flash"
- Click "Do Selected Operations"
Notes¶
TinyFPGA BX¶
Steps¶
- Install Lattice iCEcube2 (Windows 7)
- Install toolchains APIO and tinyprog from the terminal
- $ (sudo) pip install apio tinyprog
- $ apio install system scons icestorm iverilog
- $ apio drivers --serial-enable
- Add yourself to the dialout group in order for your user to be able to access serial ports
- $ sudo usermod -a -G dialout $USER
- Connect your TinyFPGA BX board and make sure the bootloader is up to date
- tinyprog --update-bootloader
- With Lattice iCEcube2 software generate programming file [Generate Bitmap] - Windows 7
- Plug the TinyFPGA BX if it is not already
- In a terminal window go to Lattice project folder and search for the programming file
- project_name/project_name_Implmnt/sbt/outpus/bitmap/xxx.bin
- Program the FPGA
- $ (sudo) tinyprog -p xxx.bin
- The configuration will reamain until you press the reset button, when it would load the bootloader
- When connected to a dumb power supply the configuration will be reloaded after 1 second
