[tiemu-devel] TiEmu: link problems

[Romain <ro...@fr...>]

Hi,

TI and their f*ucking documentation, their f*ucking hardware, their f*uck=
ing
protocol, their f*ucking...

What TI says: <<Reading the DBUs status register reset thats register. Ta=
ke to
read it once and store its value for subsequent operations.>>

What TI does in their handler:
<<
202342:	BEQ        	*+$3E [202380]   	;
202346:	MOVE.W     	(A1),D2          	; read status register
202348:	BTST       	#$6,D2           	;
20234c:	BEQ        	*+$3C [202388]   	;
202350:	MOVE.W     	($2,A0),D1       	;
202354:	MOVE.B     	($8,A0,D1.W),D0  	;
202358:	MOVE.W     	(A1),D2          	; read again
20235a:	BTST       	#$7,D2           	; and check for Status Link Err
20235e:	BNE        	*+$34 [202392]   	;
202362:	BTST       	#$6,D2           	;
202366:	BEQ.S      	*-$E [202358]    	;
>>

If the register is reset, as TI says, it's impossible to get an error !

Well, I'm feeling better for now but I spend 2 days on this ?*$#@ bug :-)=
