Subject: RE: Audio_3587 Beta Status Update
From: Mark Bright (mark_at_redbreva.co.uk)
Date: 2004-06-12

OK the problem is definitely around the modified code for the power off :
I added/modified power.c on my standard build :

void power_off(void)
{
    int i;
    char buff[20];
    /* fade out with volume control before powering down */
    for(i=mas_codec_readreg(0x10); i; i--)
        mas_codec_writereg(0x10, i);
        sleep(HZ/10); /* pause to let the chip finish it's ramping */

As per BC's modifications, and I experienced the same "Lock up's" on
attempting to power off.

Changing the code to :
void power_off(void)
{
    int i;
    char buff[20];
    /* fade out with volume control before powering down */
    for(i=mas_codec_readreg(0x10); i; i--)
    {
            snprintf(buff,20,"%08X",i);
            lcd_clear_display();
      lcd_puts(1,1,buff);
            lcd_update();
            button_get(true);
        mas_codec_writereg(0x10, i);
        sleep(HZ/10); /* pause to let the chip finish it's ramping */
    }

Shows the start value to be &00006780, which takes a LONG TIME to count
down, As Register x10 is the Volume with a value between 0 and 7F, why am I
being returned such a huge number?

The volume at the time was set to 82% (Rockbox scale)

|Do you have ICQ or AIM or something?
|
|If so email me privately with your details.
|
|I've got an idea what this "fade delay" might be.
|I don't understand it, but I'm damn sure I know where to look
|in my mods.
|
|If I am right, it may well help to identify the other weird hangs :)

|>|That is, not, how it's done ;)

|>|There are comprehensive step-by-step instructions at the
|bottom of the
|>|release notes, but to summise:
|>|Pick one rock, rename the one you pick to Audio_3587.rock
|and place it
|>|in the rocks directory.
|>|You MUST also, pick a firmware for your machine, rename this file to
|>|ajbrec.ajz and place it in your root (main) directory.
|>|
|>|However, if you are also getting weird lock-ups, I must be doing
|>|something that the v2/fm doesn't like. As I do not own such
|a device,
|>|perhaps someone who does (maybe you? :)) would like to work with me
|>|directly to solve this issue before the next release.
|>|
|>|If you can find a reliable set of events which will
|repetetively cause
|>|the same lockup, that would be perfect :)
|>|
|>|One lockup I was having in the early days was:
|>|# an mp3 is playing
|>|# the MAIN audio controls are visible on the screen # One or
|more icon
|>|is flashing (digital clip)
|>|
|>|...when the mp3 buffer emptied, my unit crashed - but I am
|99% sure I

|>|Thanks to you and all for your help beta testing, it is greatly
