00:00.09 | ali_as | Ok, so sample/preload gives you data, and boundary scan 0 crashes the board? |
00:00.22 | roxfan | boundary scan 0? |
00:00.42 | roxfan | i'm using peek 0 to test |
00:00.45 | ali_as | Instruction reg of 0 is usually boundary scan. |
00:00.48 | roxfan | and it just returns FFFF |
00:01.09 | ali_as | Formerly a mandatory part of the jtag spec, now discouraged. |
00:01.29 | roxfan | you mean extest? |
00:01.38 | ali_as | Yes, that is what I mean. |
00:11.07 | roxfan | hmm if i execute extest, next sample/preload results in dr with a lot of 1s... i wonder if i'm doing it wrong |
00:20.16 | ali_as | If the board activity dies when you execute it for the first time after power up, then something is working at least. |
00:21.18 | ali_as | prpplague mentioned his company test their boards with openocd with boundary scan using scripts. |
00:21.42 | ali_as | You could probably read/write flash the same way with some effort. |
