May 18 19:32:34 <prpplague> hmm, interesting challenge, arm920t device with _no_ bsdl file
May 18 19:32:56 <prpplague> i'm wondering if i can write a program to test generate some boundry scan info
May 18 19:40:34 <vmaster> uhh
May 18 19:41:20 <vmaster> isn't the external scan chain optional?
May 18 19:41:40 <vmaster> i.e. the lack of a bsdl file might mean there is no scan chain?
May 18 19:45:14 <prpplague> vmaster: ahh good point
May 18 19:45:29 <prpplague> vmaster: cirrus logic EP9312
May 18 19:45:31 <vmaster> what device is it?
May 18 19:45:36 <vmaster> heh
May 18 19:45:37 <prpplague> vmaster: arm920t
May 18 19:45:54 <prpplague> vmaster: has a serial bootstrap for loading an application
May 18 19:46:12 <prpplague> vmaster: so no external scan chain might be true
May 18 19:46:25 <prpplague> vmaster: just find it hard to believe that they would not include one for testing
May 18 19:49:34 <prpplague> vmaster: hmm, there are several commercial applications that proport to have access to the ep9312 bsdl
May 18 19:49:48 <prpplague> vmaster: i'm wondering if CL just doesn't want people to use it
May 18 19:50:13 <vmaster> mhh, maybe
May 18 19:53:41 <prpplague> vmaster: is there a standard register/cell that can be read to determine how many active scan chains there are?
May 18 19:55:59 <vmaster> mhh, none that i know
May 18 19:56:09 <prpplague> interesting
May 18 19:57:12 <prpplague> i've seen some jtag apps that can tell you about the length of a scanchain without a bsdl file
May 18 20:01:43 <vmaster> guess they blind-write and see how long it takes for their pattern to be returned
May 18 20:02:39 <prpplague> yea, just tested with jtagtools
