OSSC Firmware flash for the S25FL116K0XMFI041

[renegadeandy]

Hi all,

I bought the S25FL116K0XMFI041 from manufacturing, so don’t have it preflashed with firmware. I want to double check that this 8 pin chip is the thing which needs to be flashed following this process: http://junkerhq.net/xrgb/index.php?title=Updating_OSSC_via_JTAG

Assuming this is the process, it eludes to this kind of driver to write the firmware: https://www.digikey.co.uk/product-detail/en/P0302/P0302-ND/2003484

My questions are:

1/If what I have said is right, that blaster has an 8 pin connector, is there an associated 8 pin out on the OSSC V1.5 board I connect this to? If so – is that connected directly to the 16mbit flash memory linked above?

2/I assume I cannot do an SDcard firmware flash, without there being at least one version of the firmware already on the 16mbit chip.

Yes… BUT you can use a cheap Chinese USB Blaster Clone instead:

You may have to use an older Quartus Prime version for it to work… but it gets the job done as well as the original USB Blaster.

that blaster has an 8 pin connector

No… it has a 10 pin JTAG connector.

is there an associated 8 pin out on the OSSC V1.5 board I connect this to?

The OSSC Board indeed has an appropriate 10 pin counterpiece JTAG connector.

is that connected directly to the 16mbit flash memory linked above?

No. The JTAG connector on the OSSC board is connected to the FPGA… as seen in the schematics:

I assume I cannot do an SDcard firmware flash, without there being at least one version of the firmware already on the 16mbit chip.

That’s right. Without at least one existing firmware version written to the flash memory there’s no update via SD card possible.

While it’s the cheapest way to flash the firmware onto the empty chip via JTAG/USB-Blaster-Clone, it is also possible to use a programmer like this one:

But therefore you have to use the *.rbf firmware file.

Interesting thank you Morpheus_79.

So if it goes through the Cyclone, does the cyclone get connected to the external memory 16mbit chip S25FL116K0XMFI041?

Apologies for the nooby questions!

You should really take a look at the schematics:

https://www.niksula.hut.fi/~mhiienka/ossc/diy-v1.5/ossc_v1.5-diy_schematic.pdf

There (on the second page) you can see which pin of the flash memory chip connects with which pin of the FPGA.
