F256Jr	Release Candidate 17	18-Nov-2023	F256M_Wbh_Nov18th_2023_RC17_0100.jic	In light of decision to dump the big ticket items and the accessories from the store... Removed the very SPI core introduced yesterday to drive the FNXNET51 module. Removed the DP memory for the MMU and replace it back with simple Registers, which means that when you reset the system, the MMU, Page0 will be reset back to the way it was. However, the caveat is that if you change between RAM to FLASH MMU default value, you need to do a reset, either a debug reset or General Reset because the MMU is now only 32bytes in Size, so, 4 pages of 8 values.

FPGA Upgrade Guide

If you haven’t upgraded FPGAs before, below are some great videos to guide you.

You will need to download Quartus Prime Lite 18.1 Edition, since you are going to target a EP4CE15 FPGA (Cyclone 4).

Do not update to the latest version of Quartus Prime Lite, as the latest version doesn’t support that family of FPGA anymore and the software is very big.

Also, one might want to download only the "Intel® Quartus® Prime Programmer and Tools" as opposed to download the whole software by clicking on "Addition Software"

Intel Quartus Prime Lite Edition 18.1 for Windows

Intel Quartus Prime Lite Edition 18.1 for Linux

Video Guide

Note that the below Video Guide applies to both the F256K & F256Jr, despite it just being titled F256K.
