A Linux 6.2.13 Bug breaks Digilent programmer driver

[Jiajie Chen]

Hi, we recently discovered that Linux 6.2.13 introduced a bug to prevent Digilent JTAG programmer driver from working. In summary, `dadutil` fails to mmap(MMAP_32BIT) due to regression in Linux 6.2.13. You may see the following error running `dadutil enum`:

 

ERROR: DmgrSetNetworkEnumTimeout failed, erc = 3090

 

And Vivado will not be able to recognize Digilent JTAG programmer. Hope this helps anyone using new Linux kernel for FPGA development.

Hi @Jiajie Chen,

Thank you for sharing this; I don't think there will be much Digilent can do to address this (though I'm not a Linux expert, so I could be wrong on this), but I have let our Adept developer know about this on the off chance there is something we can do on our end.

Thanks,
