Description

in file hwicap.c, id code table series_ultra_plus_idcodes is missing some entries, as per UG570 (v1.20.1) March 4, 2025
UltraScale Architecture Configuration document, table Table 5: JTAG and IDCODE for UltraScale Architecture-based FPGAs on p.20.

For instance, AU15P (X4ac2093) is missing.

I'm counting 29 Ultrascale+ devices (5 artix, 7 kintex, 17 virtex). Yet the array size is 28 (with wrong array size specified as per https://github.com/Xilinx/embeddedsw/issues/333) , so the AU15P looks to be missing from the array.

Sadly, this is the one part we are using...

Layout like this could help quickly identifying supported devices rather than cross-referring to the ug:

static u32 series_ultra_plus_idcodes[] = { 0x4A63093, // KU3P ... };

Research direction

Start in hwicap.c and inspect the series_ultra_plus_idcodes array alongside UG570 v1.20.1, Table 5 on page 20. Compare the listed UltraScale+ devices and ID codes, including AU15P (X4ac2093), and verify the declared array size against the complete set of supported devices. Done means the missing entries and incorrect size are corrected and the table is represented accurately.
