Hi, This question is for all the users of the AMD alchemy db1550: What is the frequency you use for the triplet (CPU core / System bus / SDRAM bus)? Since the version 2.25 of YAMON the freq is based on the rotary switch S4: HEX Rotary Switch S4 (# = CPU_CORE / SYS_BUS / SDRAM_BUS in MHz): 0 = 192/ 96/ 96 , 1 = 336/168/168 , 2 = 396/198/ 99 , 3 = 396/198/198 4 = 492/123/123 , 5 = 492/164/164 , 6 = 492/246/123 Thanks, David SANCHEZ -----Message d'origine----- De : Sergei Shtylylov [mailto:sshtylyov@xxxxxxxxxxxxx] Envoyé : lundi 5 décembre 2005 13:00 À : David Sanchez; Linux MIPS Development Objet : Re: Au1550 system bus masters issue Hello.

Oops, I was talking of Au1500 step AB, Au1550 doesn't have CONFIG.OD bit errata... WBR, Sergei
