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

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