| 07:27.52 | Viltapi | hello |
| 07:27.54 | methril|work | lo127: morning |
| 07:28.06 | methril|work | lo127: how is your .srec booting? |
| 07:30.11 | lo127 | methril|work, its transferring fine, checksum is ok, but it restarts the board immediately upon run |
| 07:30.37 | methril|work | maybe a bad root fs ? |
| 07:31.34 | lo127 | not sure, I need a serial connection to see what is happening |
| 07:33.27 | lo127 | the problem is that the bootloader only handles one interface at the time, ethernet or serial |
| 07:51.16 | methril|work | it's your board supported by u-boot? |
| 07:51.35 | methril|work | put u-boot and boot the kernel easy |

| 12:46.41 | lo127 | boris_OmegA, you still here? |
| 12:50.02 | boris_OmegA | yes but don't have time right now, lo127, but you can leave me your question, i'll have a look later :) |
| 12:52.50 | lo127 | cool, basically my question is if this few line would produce any output on the uart: http://codepad.org/fj4hbYTx |
| 12:53.31 | lo127 | (they don't) |
| 12:57.44 | boris_OmegA | on what arch, lo127 ? |
| 12:58.06 | boris_OmegA | and what os ? |
| 13:02.08 | lo127 | its running from a custom bootloader on powerpc arch |
| 13:02.42 | lo127 | think the main thing is right, just want to know if I missed something (which I probably have) |
| 13:08.10 | boris_OmegA | i guess there is a pin to set to make UART transmit |
| 13:08.39 | lo127 | thats true |
| 13:08.41 | boris_OmegA | lo127, you must have a look to your UART chip documentation |
| 13:08.59 | boris_OmegA | maybe you'll find this pin ? |
| 13:09.34 | boris_OmegA | or check if your bootloader have functions for manipulating UART devices |
| 13:12.38 | methril|work | lo127: looks like you didn't initialize the UART, the baudrate, ... |
| 13:13.13 | lo127 | methril|work, the bootloader does that |
| 13:13.24 | methril|work | but it inits the uart somewhere ... |
| 13:14.50 | methril|work | and while(1), only sending, could overflow, your TX buff |
| 13:15.01 | methril|work | you need a delay or something like that |
| 13:15.35 | boris_OmegA | yes |
| 13:15.40 | lo127 | methril|work, I just want any output |
| 13:15.46 | lo127 | gibberish is fine for me :) |
| 13:15.47 | boris_OmegA | but i think it never send anything ... |
| 13:15.56 | lo127 | boris_OmegA, I can confirm that :) |
| 13:16.10 | methril|work | then initializing of the UART register has to be done ;) |
| 13:16.16 | methril|work | did you check with an oscilloscope? |
| 13:16.34 | methril|work | maybe your baudrate is not equal to your port listening baudrate |
| 13:16.37 | boris_OmegA | you must have some registries to initialize your uart , and some registry or pin to command TX |
| 13:17.03 | lo127 | I'm reading the cpu documentation now |
| 13:17.05 | boris_OmegA | if baudrate isn't good, often there is an output ..something bad, but something :) |
| 13:17.27 | boris_OmegA | but oscilloscop is a good way, anyway |
| 13:17.30 | lo127 | the uart is working, the bootloader outputs fine untill i "run program uart_test" |
| 13:18.05 | lo127 | then it leaves control to my program, which is totally silent |
| 13:20.51 | boris_OmegA | do you know what uart_test does ? |
| 13:21.04 | boris_OmegA | if you have src, this is a good way to learn ^^ |
| 13:21.55 | lo127 | thats my program :) |
| 13:21.58 | lo127 | I just posted |
| 13:22.45 | lo127 | I'm writing a new version of it |
| 13:24.19 | lo127 | I was hoping my simple program would print tons on L (and/or gibberish) verifying the cross compilation and srec creation |
| 13:24.52 | lo127 | as I said, the bootloader has setup the uart and I was able to load my program over it |
| 13:25.05 | lo127 | think I need to use: "UART_RTS[0:1] O 2 1 Request to send UART0 and UART1"? |

| 13:26.32 | boris_OmegA | but |
| 13:26.42 | methril|work | and maybe you've to check if you're sending some bytes on the serial |
| 13:26.43 | boris_OmegA | do you try to use your debug uart port ? |
