Thanks for CCing me, I assume this is a driver for that "altera_epcq_controller" which you can synthesise into your FPGA, is that correct? Is there an Hard IP variant of this controller in the public or is this purely Soft IP? Also, I cannot find any documentation for this IP block even if I search through Quartus/QSys, is there any proper documentation available anywhere? [...] Best regards, Marek Vasut
