Hello,

thanks for the new version. The matrix keyboard is now working . Also, it was very easy to adapt the 'fs-matrix-keypad.h' to our own keyboard layout with only 24 keys.

Thanks

Can you be more exact, please, when will be soon? We must use the NetDCUA5 as a replacement for the NetDCU10, and we do not have very much of them left. From May last year we have been waiting for a first sample of the NetDCUA5 until December. Until then, we are waiting for a Linux that is as complete as that on the NetDCU10 (missing e.g. matrix keyboard), and now the matrix keyboard is not working. We cannot loose more time.

Today I installed the new fsvybrid V2.0 on my NetDCUA5. Woking, ok. Then I compiled a new kernel to activate the matrix keyboard. This leeds to a kernel - oops while booting. I changed the kernel configuration back to not using the matrix keyboard, this kernel is working ok. I tried a few more configs, diaable or enable several rows/columns, disable or enable the SPI port - always the same result: whenever the matrix keyboard is enabled, the kernel crashes during boot. Following is the Backtrace of the kernel:
