Upload-Tool for Booting a TIVA over SPI or i2c under Linux?

Hello Marku,

While TI does not market any such tool, there is one from Aadvark that may be used to create an application.

Although obvious to me, it doesn't mean it's obvious to anyone else ... to rephrase and hopefully clarify:

I'm looking for sourcecode to support the i2c or spi serial download and updating of firmware on/to the TIVA from a Linux host.

While there are sourcecode examples of the host side of things for UART and USB (lm4tools), i've failed to find anything for i2c or spi.

The tool should support
- a fresh, unprogrammed chip
- ROM based update via ROM_UpdateI2C (void) or ROM_UpdateSSI (void)
- Flash based update while running the "boot_serial" bootloader from the tivaware package

Hello Markus,

The I2C or SPI follows the same protocol structure as UART. The only difference being that it is not Auto Bauding on the I2C and SPI. The data rates are fixed on both Master and Slave. The requirement 2 and 3 are more for the TM4C device than it is for the tool.

Hi Amit,

yes, i know that.
But is there compilable source _available_ - or will i have to create one myself ... Not a big deal, but i would like to avoid writing yet another version of the same code ...

Cheers,
Markus

Hello Markus

No, there is not a source code available yet. We do plan it to be added as part of Boot Loader User Guide conversion to Application Note

Hi Amit,

thanks for your efforts!

Any of the the other users here willing and able to share sourcecode?

Hello Markus

We generally rely on the community to provide their code!!!

Additional help sought....
