CarlFKI have a pi hostname fomu-dev07:57
CarlFKanyone have a guess at user/pw?07:57
CarlFKpi/raspberry isn't it07:57
CarlFKfomu fomu08:01

xobsfomu / fomudev08:26
CarlFKthanks08:55
CarlFKlookie my jig https://matrix.org/_matrix/media/v1/download/matrix.org/YdyLLkXNbWbphzSYFRDDUgOO08:57
CarlFKI have a fomu in the jig..09:20
CarlFKis there something I can do to verify the pogos are hitting the pads?09:20
xobsCarlFK: You could run "fomu-flash -i" to see if you can see the ID.09:21
CarlFKoh oh... nothing but ff's09:22
xobsIf you apply 3.3V and GND, you ought to see that voltage on the USB pads.09:23
xobsSo that way you can verify those pins are hitting it, at least.09:23
CarlFKI knew I should have hadcfk022809:33
CarlFK ... pogos for the usb pads09:35
CarlFKI get the pulsing led... sometimes09:37
CarlFKmanufacture ID changed from ff to 7f09:40
xobsThat indicates that pin is probably floating.09:41
xobsI'm sure it'll go to 0 by you just touching the pin.09:41
xobsWhich means either CS isn't wired correctly, power isn't connected, or of course MISO isn't connected.09:42
CarlFKmind double checking my setup10:06
CarlFKhttps://matrix.org/_matrix/media/v1/download/matrix.org/NHtOErbAAwitdayonjlIvCAn10:06
CarlFKblack to GND (can't see it) and brown goes nowhere10:06
CarlFKhttps://matrix.org/_matrix/media/v1/download/matrix.org/SHtqakioRbtKDvOgxWeGglTX  im guessing the spots are where the pins are hitting10:19

CarlFK5:30am - I should go home10:33
xobsSeems about right.10:34
xobsHere's the reference map: https://github.com/im-tomu/fomu-factory-test/tree/master/jig10:34
tpbTitle: fomu-factory-test/jig at master · im-tomu/fomu-factory-test · GitHub (at github.com)10:34
xobsNote: You have no SPI_IO2 or SPI_IO3.10:34
CarlFKthats what I used to wire it up10:34
CarlFKwhat would those 2 connect to?10:34
xobsIf you have 4-wire SPI, it connects to the other two wires.10:35
xobsIt seems wired up correctly from the pictures you sent.10:36
CarlFKwhat should the Manufacturer ID be?10:37
xobsLooks like some variant of "0x1f148601"10:39

CarlFKI have a fomu that pulses the LED when given power.  windows shows bootloader version 1.8.1 - how do I update that?21:43
CarlFKmithro: ^^21:45
mithroI don't know if we have an update procedure at the moment?21:46
mithroxobs: ^21:46
CarlFKwhat about using a jig?21:47
CarlFKmithro: does hooking the fumu to the pi's spi bus stop blink.bin from pulsing the LED?21:53
mithroCarlFK: sure21:55
mithroCarlFK: just like programming from scratch21:55
CarlFKmithro: I've been assuming it stopped blinking because my pins were not lined up right21:56
CarlFKmithro: where/how/help ... do I get the 1.8.7 boot loader ?21:57
CarlFKwoo.. we got blink.bin to .. blink21:57
CarlFKmithro: what pins do I need to disconnect to let blink run?22:05
mithroCarlFK: dunno22:27
CarlFKmithro: where do we get 1.8.7 boot loader?22:27

CarlFKmithro: To load a new bitstream, use the dfu-util -D command.  https://github.com/im-tomu/foboot23:28

mithroCarlFK: that is for the user spac23:28
CarlFKmithro: dfu-util isn' on the pi, and the fs is read only.. any idea how to ...23:28
CarlFKmithro: ok, lets backup - how do I get 1.9.1  onto the fomu?23:30
mithroCarlFK: you have top options - (a) flash using a rig, (b) bug xobs to tell you how to do it over dfu23:31
CarlFKmithro: I have a rig23:32
mithroCarlFK: then use fomu-flash23:32
