Hi everyone,
in my project I want to stream thermal video data via USB. The FX3 acts as a bridge between a FPGA and the USB-Host. Further I use the TI HD3SS3220 Type C Portcontroller.
The FX3 should communicate to the Portcontroller via I²C and the FPGA will send its data via the slave fifo interface, which i want to make 32 bits wide. The FX3 won't have to manipulate the data, as the FPGA will do all the processing.
So, if I understood this right, I could keep the power domain of the SPI unpowered, if I boot the FX3 from I²C-EEPROM.
I'm worried to get in trouble with the Bootimage size, as I have no experience with the FX3. Do you think the 256kB are sufficient? Or should I consider using a larger Flash memory?
Thank you for your support
Best regards
Dennis

Hi Dennis,
Generally 256KB should be enough for a FX3 only application. In most cases, the firmware img file will not larger than 200KB.
