| 15:24 | topi` | it seems ttymxc3 doesn't work on my HB Gate :( |
| 15:25 | topi` | my program gets stuck, and if I interurpt it, it's blocking on a line like n = os.write(self.fd, data) |
| 15:25 | topi` | where fd is most probably the /dev/ttymxc3 I passed to pyserial |
| 15:26 | topi` | well, this very same code works on /dev/ttymxc0 of my HB Pro (the Hummingboard 1 series) |
| 15:35 | topi` | there seem to be only 6 interrupts to IRQ 61 and they're not increasing while I try to type on either minicom |
| 15:37 | topi` | I can't surely be using the wrong pins, since the mikrobus pins are clearly labeled on the silkscreen... |
| 15:38 | topi` | the usbserial cable is not to blame, since if I change the cable to the UART connector next to LVDS out, I get a login prompt.. |
| 15:39 | topi` | how can I reverse-engineer the .dtb in /boot? to make it a .dts again |
| 15:39 | topi` | oh, there seems to be device-tree in /pro |
| 15:40 | vpeter | topi`: dtc -I dtb input.dtb -O dts -o output.dtd |
| 15:45 | topi` | it seems serial0 is different from others |
| 15:45 | topi` | it's /soc/aips-bus@02000000/spba-bus@02000000/ whereas the other serials are just /serial and on another aips-bus |
| 15:46 | topi` | might this explain why ttymxc0 works and ttymxc3 does not? |
| 17:02 | topi` | rabeeh: about the HB Edge enclosure, is the big hole next to the HDMI connector meant for antennas? |
| 17:02 | rabeeh | yes |
| 17:02 | topi` | rabeeh: we need 2 antennas (or even more), so I'm trying to look for a spot for drilling a hole for the second antenna. Any suggestions? |
| 17:02 | rabeeh | the aluminum is an rf cage; so external antenna is required |
| 17:02 | topi` | we need 1 antenna for the wifi, and 1 antenna for a 3G/4G modem |
| 17:03 | topi` | we don't need analog audio (the audio will go to a display via HDMI) so those holes could be used for antenna |
| 17:06 | topi` | do you remember which component goes to J35? I have just a Gate here in front of me and it is not soldered. On that spot there seems to be a hole in the aluminium as well |
| 17:07 | topi` | (it's in color olive in the 3D model of the enclosure, which is what I'm studying) |
| 17:08 | topi` | otherwise; congratulations on excellent work on the enclosure, the SIM slot is easily accessible on the bottom |
| 17:08 | topi` | (I've seen cases where the SIM is not that easily accessable...) |
| 17:42 | topi` | jnettlet: there seems to be a connector J35 where UART2 tx/rx are routed. which ttymcx* device would this be mapped to, in the kernel? |
| 17:42 | topi` | the UART2 seems to be shared with the RS485 circuit |
| 18:30 | jnettlet | That is the ttymxc3, the rs485 is an add-on circuit |
