Lastly, this may not be something you wish to do, but the 3.x tool chain does not need any separate java installation and is all 64-bit. However, you would need to port your app to the 3.x tools. I'm not saying do this to fix your problem, just providing complete info. I'm sure you have your ...

Don't know where I got 2.8.9 from, but any 2.8.7 through 2.9.7 runs on a machine with win 11 natively installed per the above comment. Just confirming so you know its something with the setup, not the installer or tools.

Does the example work from the command line using make and no changes to the makefile?

Remember to run \nburn\setenv.bat first.

On a clean win 11 build there is no issue installing and running 2.8.9 with 32-bit java 8 with eclipse or command line. Something must be going on with all the vm stuff ...

Does the example at \nburn\examples\SPI\PicKitSerialSPIDemoBd help at all? I don't know if it switches polarity.

I think I am not understanding something in the original post, so please let me know. Wouldn't you only set the chip select after the configuration?

Hello ephogy,

With mutiple releases and many products with specific drivers, people will always need to know the nndk version and hardware platform to be able to help. I think that is why this has not had an answer and so many views.

Sorry for the I2C reference, I mis-typed. There is a pic kit for spi too: C:\nburn\examples\PlatformSpecific\SPI\PicKitSerialSPIDemoBd. I think it might just be a small spi than you are using.

Demonstrates the use of 7 Microchip SPI Peripherals:
- 25LC020A 2K SPI Bus Serial EEPROM
- TC77-5.0 ...

Have you looked at the PicKitI2C example for comparison? It reads/writes an EEPROM. The example docs are here:

Might be good to compare the two and see if there are any significant differences ...

Just a note for anyone using legacy tools, command line builds do not use java. We have made makefiles very easy to use. If you look at any example you will find a makefile. All you need to do is add your source files, all the other complexity is already done. At that point you can still eclipse, or ...

Thanks for the followup, although surprised java8 32-bit did not work. If you have both 32 and 64 bit installed, it could be a path problem. But installing from our java link is the best.
