Dear all I am Binh, from Vietnam. I try to use linux alsa driver on Xilinx XUPV2P board. This board has LM4550 AC97 audio codec same to ML403 board. -I use EDK 9.1i sp2 -I also use opb_ac97_controller_ref_v1_00_a as requirement in ml403-ac97cr.c -I connect both Playback_Interrupt and Record_Interrupt to Interrupt controller -I use ELDK as cross compiler, and download kernel from <http://xilinx.wikidot.com> xilinx.wikidot.com -I config kernel: device drivers->sound card support->Advanced linux sound architecture-> Generic sound devices -> Xilinx ML403 AC97 controller reference
(I combine kernel and alsa driver into one kernel file)
But when I boot the board there are messages:
" Advanced Linux Sound Architecture dirver version 1.0.20
Alsa device list:
No soundcards found"
Do I miss any steps?
Thank in advance
Best regards
Binh NT
