00:10.47 | Turl | hno: A10 can't output >1080p as far as I understood though |
00:11.40 | Turl | hno: it might be able to decode 2160p, but I guess it's downscaled |
00:11.51 | ManoftheSea | Oh? Did the 2160p get defined as 1080 + 1080? |
00:11.56 | Turl | or maybe it's a marketing name for 2x 1080p decoding streams |
00:12.29 | mnemoc | I believe his comment was more on the line. "do you have a >1080p tv to support your claim that 4k is not supported?" |
00:13.13 | Turl | 2160p is not 4K anyway |
00:14.31 | mnemoc | sorry. I'm not very into HD.... I only use the TV to watch a DVD once per month and that's 720p iirc |
00:15.04 | mnemoc | I had the idea that 4k was a way of telling that by doubling the weight you are 4x the actual surface |
00:15.35 | Turl | DVDs are not 720p :P |
00:15.46 | Turl | 4K means ~4000 on height |

00:19.09 | Turl | mnemoc: compare the 'dvd' piece to the 4K :P |
00:19.28 | mnemoc | I think I have 4-5 hdmi cables and one "full hd" tv.... but my daughter tends to perfer to connect the VGA from the computer to the tv than the hdmi from the tablet.... I think it's because youtube restricts what videos can be playd there |
00:19.53 | Turl | mnemoc: I connect the vga + 3.5mm too |
00:19.57 | ManoftheSea | what kind of connector do you use? |
00:20.04 | Turl | mnemoc: because I'm cheap and my china HDMI hasn't arrived yet :P |
00:20.10 | ManoftheSea | I mean, the signal on that must be running remarkably fast. |

20:31.20 | hno | frantisheq, yes, but not sure how to do it with Debian It's done with an initramdisk that configures network and mounts the root. |

20:41.33 | hno | bkero, to get HDMI out you need to get very very far in the boot process. THere is a million things that can go wrogn before. |
20:41.55 | hno | so UART is hightly recommended. |
20:42.37 | bkero | hno: Nobody's found a UART on the motherboard yet. I'm wondering if I should either go sniff one out, or if I could use the android kernel it came with, and then try to get that to work, just with using a different userland |
20:43.10 | bkero | hno: I was able to dd if=/dev/block/nanda | gzip -c > /mnt/sdcard/nanda.gz, then copy it off, and mount it on my laptop to get a working boot partition. |
20:43.11 | hno | We think UART is on the leftmost two pads in the block of 4 pads on the board edge just next to the CPU. |

20:44.02 | bkero | hno: 2 pad or 3? |
20:44.17 | hno | for probing you just need wires and a 3.3V UART. |
20:44.29 | bkero | I've got my bus pirate, that'll be good enough |
20:44.30 | hno | you also need to find GND somewhere. |

20:44.43 | hno | yes |
20:45.11 | bkero | are you also working with an mk802 stick? |
20:46.07 | hno | Connect GND somewhere. Then the RX wire of your UART (the input wire where the UART receives data, not the wire that should be connected to board RX) and look for the MK802 TX pad. |
20:46.26 | hno | it should be quite chattery when you boot. |

21:50.38 | hno | fashinatng, the Mele do not have any form of battery or even any larger capacitor from what I can tell, yet the RTC keeps running when power is removed. |

21:56.35 | Xlab | RX data reading works fine, but I'm unable to send anything with TX :/ |
21:56.50 | bkero | hno: yea on my beagle |
21:57.20 | Xlab | By datasheet, SDC0_CLK is TX and SDC0_D3 (probably CD) is RX |
21:59.30 | Xlab | TX sends me /dev/ttyS0, but RX don't read anything :( |
22:01.48 | hno | Xlab, you got the right pin? |
22:02.16 | Xlab | ? |
22:02.31 | Xlab | Data3 pin is CD pin on my sniffer |
22:03.10 | Xlab | But i tried them all, of course |
22:03.26 | zenitraM | mmhm, yours is not the first case of input not working on a tablet i've read here |
22:05.04 | hno | could be as simple as https://github.com/hno/uboot-allwinner/commit/bf233ed95fdf1fda9df75de902d101463fd5cd56 |
22:05.40 | zenitraM | DonkeyHotei had the same problem, and it wasn't u-boot fault as input didn't work on Android either |
22:05.51 | zenitraM | don't know if he fixed it |
22:06.54 | hno | If u-boot leaves PB23 as UART RX then things likely break if SD is also configured for UART RX. |

22:09.49 | hno | if that's the cause then it should be fixable by adding psuedo-tty pins setting PB22 & PB23 as GPIO input, or by uploading a modified u-boot. |
22:14.25 | hno | Xlab, try adding the following to uart_para0 |
22:14.49 | hno | uart_tx2 = PB22<0> |
22:14.55 | hno | uart_rx2 = PB23<0> |
22:26.44 | hno | pin function names do not matter. What matters is the PB23<0> that sets PB23 pin as GPIO INPUT. |
22:36.49 | Xlab | uart_debug_tx2 = port:PB22<0> |
22:36.49 | Xlab | uart_debug_rx2 = port:PB23<0> |
22:36.56 | Xlab | Should i add this too? |
22:38.26 | Xlab | Hmmm |
22:38.54 | Xlab | fex2bin utility just truncates uart_tx2 & uart_rx2 values |
22:39.22 | Xlab | fex2bin and then bin2fex, and they're gone |
22:51.14 | zenitraM | it doesn't truncate them, it's just that leaving the values to 0 produces the same output that not putting any value there |
22:58.11 | Xlab | nothing has changed :( |
23:02.03 | Xlab | afk |

23:53.12 | bkero | hno: the mk802 board has 4 pads next to the CPU, not two. :/ and my multimeter is acting busted, so I'm going to have to try with the bus pirate. |
23:56.49 | bkero | Hrm, 3.3v coming from two pins, 2.19 coming from one pin |
