<CarlFK1> openFPGALoader -b arty --reset
<CarlFK1> Jtag frequency : requested 10.00MHz -> real 10.00MHz
<CarlFK1> this is more an Arty question... how do I get the default/factory bitstream back?
<CarlFK1> I thought --reset but it seems I replaced it with my own
Guest65 has joined #openFPGALoader
<Guest65> I have this board, what would it take to add support to openFPGAloader
<Guest65> it's altera cyclone iv
<Guest65> also, can you recommend any collections of bitstreams for cyclone iv, eg crypto and hash algorithm implementations
<Guest65> I know that it's not that powerful but I would like to poc for learning how fpga-s work
<CarlFK1> poc?
<trabucayre> CarlFK1: --reset is used to force FPGA to reload SRAM with SPI flash content
<trabucayre> If you have a custom bitstream into flash this one will be loaded
<trabucayre> Guest65: a bitstream is dedicated for a couple FPGA+board so you have to integrate IP into a project dedicated for your target board

<CarlFK1> trabucayre: yeah, so I am trying to --dump-flash from a unflashed board, and failing
<CarlFK1> openFPGALoader -b arty --dump-flash --file-size 134217728 --bitstream a7.bit
<CarlFK1> openFPGALoader -b arty pi34/a7.bit
<CarlFK1> Parse file Error: Failed to program FPGA: basic_string::substr: __pos (which is 4294949689) > this->size() (which is 134217728)
<CarlFK1> --file-size 268435456 ... try to load it... Parse file Killed

<CarlFK1> https://forum.digilent.com/topic/29894-factory-bitstream-arty-a7/ lets see if someone can get me the original
Guest65 has joined #openFPGALoader
<Guest65> ok
<Guest65> I guess I'll have to start by findinga quick course for fgpa-s
<Guest65> coursera or udemy or somesuch

<Guest65> subscribed to this one, looks promising
