Mity CPU Platforms » MitySOM-5CSX Altera Cyclone V

Hi Darius,

The console USB connector is simply a UART interface. You can use this to talk to uBoot and the Linux console to configure the flash. If you want to go through JTAG, the white connector on the top of the MitySOM will accept the JTAG adapter card.

Thanks,

Adam,

Thank you for your reply. How would I need to go about configuring the flash via the console USB connector?

Hi Darius,

To start, I'm not sure what your hardware setup is, so I will assume you are working with a Dev Board or a board that can boot from an SD Card. When that boots, there is a very brief preloader configuration, then uBoot starts and counts down from 5 seconds. Within that time, you can send a character through the console interface (connect serial terminal app with settings of 115200,8,N,1) to halt the boot process and wait at the uBoot command prompt. Assuming you are able to get to this point, you can follow the info on the Wiki to program the QSPI NOR Flash. Note that different BSEL (Boot Select) values are required to boot from SD v.s. QSPI NOR. On the Dev Board, simply adjust the DIP Switch settings in switch positions 10,9,8. For SD Card, use "101" by setting them Off,On,Off. For QSPI NOR, use "110" by setting them Off,Off,On respectively for positions 10,9,8.

Please let us know if you run into more hurtles.
