Honored ContributorOpencores I2C Core and uClinux Driver
I have added an Altera Avalon SOPC Builder I2C Master component based on the Opencores I2C Host.
http://via.dynalias.org/svn/fpga/cores/i2c_master/trunk/ (http://via.dynalias.org/svn/fpga/cores/i2c_master/trunk/) Either download using the web, or use SVN to check out the project.. I simply created a wrapper for this and the necessary files to drop this component onto the Avalon bus, so I don't take any credit for this core. This will just make it easier for new people not wishing to go through this hassle. Also, I am working on getting the uClinux driver up and running. There is an Opencores driver already included in 2.6.16.1, so I will just be modifying/testing that and posting the results here. J16 Replies
Altera_ForumThe kernel patch for 2.6.16.1 is located here:
http://via.dynalias.org/svn/uclinux/patche..._core/tags/1.0/ (http://via.dynalias.org/svn/uclinux/patches/i2c_core/tags/1.0/) This is only a simple modification of the Mictronix driver, so that it compiles with a single core. Credit goes to Microtronix for the core.- Altera_Forum

It is due to kernel version changed to 2.6.17 in uClinux-dist-20060803.
I will check it tommorow. - Altera_Forum
The include file is missing.
Updated in the nios2 patch ver 10. - Altera_Forum

hippo,
In the customise kernel settings --> device driver --> i2c When I added i2c algorithms --> Opencores i2c interface i2c hardware bus support --> opencores i2c adapter It gives error when generating the zImage Pls help. - Altera_Forum
update again, nios2 patch ver 11.
fixup i2c for DE2. - Altera_Forum

I think your source is OVER patched. ?
Did you remove old patchby reverser patch ? Check "update the patches" in the UclinuxDist wiki page. Now you should remove old uCLinux-dist dir, and reinstall. - Altera_Forum
hippo, i am trying it NOW ... standby.
