    What are the limitations of Altera NIOS II Demo?

    @ltera NIOS II Demo Hello Regnum, The evaluation version of Nios II is time limited. That means the core runs for a limited time (I think one hour) if the JTAG connection (PC to FPGA) will be disconnected. The RTOS installation files are also missing. Regards, cube007

    Initializing SD Card in SD bus mode

    Hello, For getting the best performance I would like to implement a SD card IP within an FPGA which communicates with a SD Card in SD bus mode. As far as I know the first steps are as follows: 1. Send command CMD55 2. Send command ACMD41 with OCR data 3. Wait for response to the ACMD41...

    How to develop software and hardware in Nios 2.2 kit?

    Nios 2.2 Hello river78, You can use the “PLD, SPLD, GAL, CPLD, FPGA Design“ forum here at EDABoard or the www.niosforum.com which is very good in Nios topics. Unfortunately Nios 2.2 is very old. So you wouldn’t get a lot of support. The actual version Nios II 5.1. Bye, cube007

    nios and microblaze?which is better?

    Hello William.Yao, Please give some more details about these bugs? Until now I have been working with Nios and Nios II for about 1.5 years. And yes I encountered problems with some components. But I believe Xilinx has the same problems. And both companies are working hard for there customers to...

    [REQ] RSA key-generator

    Hello, I think I got the solution. Tools like Puttygen are using Base64 (https://en.wikipedia.org/wiki/Base64) for encoding data like keys. Regards, cube007

    [REQ] RSA key-generator

    Hello, For some testing I’m working with “RSAEURO - RSA Library compatible with RSAREF(tm) 2.0.”. For encryption and decryption the lib needs some keys of course. The values of n, e and d have to be in hex. Now I’m looking for different RSA key-generators which are producing such hex keys which...

    Getting Code (or Bit Code) of an Altera Max 7000 series chip

    Getting Code (or Bit Code) of an @ltera Max 7000 series chip Hello happs, i) I definitely know that it’s available in Quartus. I think this option must be in MAX+Plus II too. Just take the software you used for development or did you lost the software too? :-) ii) IMO if you get an error...

    Getting Code (or Bit Code) of an Altera Max 7000 series chip

    Getting Code (or Bit Code) of an @ltera Max 7000 series chip Hello happs, i) IMO you will never get back the source code because this one isn’t stored. The device holds information about the organisation of the macrocells and not the source code! ii) Yes you can read out the MAX device if the...

    Nios and TCP/IP stack

    eCos is supporting different TCP/IP stacks and different NICs. The configuration tool of eCos is doing a lot of work for the developers but if you want to build up a stable and fast system a lot of knowledge and work is needed. IMO that’s the matter with all operating systems in the embedded world.
