06:07 Jessykinha hi
14:32 topi` jnettlet: I managed to create a souped-up cable usbA <-> usbA with D+ and D- crossed. I have an older HB Pro here to test it with, is there any LED that should lit up if I connect a +5V power source to that USB-OTG port?
14:33 topi` or any other means to actually verify that the cable works and is able to provide sufficient amperage for the usb-otg flashing/efusing process?
15:31 jnettlet topi`, you need to power the target board separately that is why you need the resistor. If it works, lsusb on the host will show freescale device in recovery mode.
15:47 topi` I looked at the "older" document, and it says green and white cables should be connected to each other as-is, and not crossed like I did
15:47 topi` I guess I'll redo the cabling :)
15:47 topi` my soldering iron was so shitty that I decided to do shrink-tubing instead
17:02 jnettlet I am working on a hardware developer platform to make this much easier. Finally found a decent chip to use.
18:51 topi` what's the best way to identify whether the HB SOM has broadcom or wilink8 chip? "lsusb" won't work...
18:51 topi` does wilink8 connect via SDHC?
18:53 topi` I guess there is no such thing as a "lssdio";)
19:00 topi` I see the sdhcs in the /sys/firmware/devicetree but it's nearly impossible to know which is a SD card and which is a SDIO device like wifi chip
19:09 jnettlet topi`, wilink8 has a big silver chip on it next to the antenna, the BCM variants are black chips.
19:10 jnettlet topi`, but modern u-boots will detect them properly and add a -som-15 suffix to the dtb name.
19:10 topi` ok, interesting
19:11 topi` I just want to be able to handle both v1.5 soms and the newer ones :) I want to give them custom hostapd flags
19:11 topi` I think the Wilink8 can handle advanced 802.11n flags like RX-STBC1, SHORT-GI-20 etc
19:11 jnettlet topi`, yes it can
19:11 jnettlet for detection....let me think about it. You should be able to read the device-tree properties.
19:12 jnettlet but you will need additional patches for upstream.
19:12 topi` does UBOOT pass the kernel which .dtb it used?
21:22 Artox topi`: the product name is available somewhere in /sys
21:23 Artox err proc /proc/device-tree/model
21:24 Artox but I have a feeling that string doesn't tell you about the SoM
21:24 Artox it could, but apparently it doesn't
21:25 Artox hah, I know
21:26 Artox https://github.com/mxOBS/deb-pkg_cuboxi-firmware-wireless/blob/master/debian/cuboxi-firmware-wireless-bluetooth.brcm_patchram_plus.init
21:26 Artox there should be a vendor id available too somewhere
21:27 Artox ; /sys/bus/sdio/devices/mmc1\:0001\:2/vendor and /sys/bus/sdio/devices/mmc1\:0001\:2/device
21:28 Artox or perhaps better yet: /sys/class/net/wlan0/device/{vendor,device}
