Downloading software to the CPLD chip from another processor

[Altera_Forum]

Hello, 

I have an embedded application where I am using the MAX V CPLD chip and also an ARM processor. I need to be able to program the MAX V CPLD chip from the ARM processor. The way the CPLD is programmed now is by jtag from a PC. Is there any information about doing this or another way of programming the CPLD without using Jtag? Any help would be greatly appreciated.  Thank You

Maybe you can bitbang programming bitstream?

Check out this link - 

https://www.altera.com/support/support-resources/download/programming/jam.html  it's the page for the Altera Jam STAPL software. There's source for programming devices from a cpu. I've done it before with a X****x device and an embedded cpu, should work the same way.  Kevin

Programming devices via JTAG is possible. Older generation devices were supported by Altera's JRunner software (and maybe newer devices are too). Take a look in the MAX V handbook and look at the IEEE 1532 details. The "Programming Sequence" section looks like it provides enough detail so that you could create your own programmer. I'd recommend buying a low-cost MAX V kit and trying that procedure, or post a new thread asking if anyone on the forum has used an IEEE 1532 programmer. 

 Programming a MAX V via IEEE 1532 instructions could easily be tested using an FTDI C232H cable (assuming the MAX V JTAG interface was also 3.3V, otherwise you'll need level translators).  Cheers, Dave
