I'm talking about the aic23 stero codec which the E3 seems to have 2 of ?! You don't need the DSP either as the BSP that sends the sound samples (via I2S) can be mapped to either the DSP or the CPU.
Er, really? You have this working?
Well, what to you mean by working ;). I looked through the E3 config for the 2.4 kernel and found that it had enabled support for the the aic23 stero codec and after a bit of light hacking I got it to complie under 2.6. The aic23 I2C driver probes for the device and will only try to attach to if it got an ack back from a chip so either the I2C bus is in a state which means it always thinks it has an ack, there is another I2C chip at the same address, or there are 2 aic23 stero codecs on the E3. As I haven't taken mine apart I don't know which it is.
I have DMA interrupts & I2C interrupts, but no sound as yet.
Thanks for the FB patch's Jonathan, but your E3_defconfig doesn't seem to have been updated to enable the FB :-(. In fact your patchs like very much like the changes I have made (great minds ;), however, your patch (like my version) only seem only yeild a blue display on my E3 (different hardware version?!) I'll have a play around this weekend to see if I can find you what's wrong. In the mean time would it be possible to post your working FB config plus a kernel uImage (just to make sure that we are running execatly the same code).
That patch doesn't have the FB enabled because it doesn't work in it. It has working NAND and an updated keymap over my first patch.
I'm going to have a new patch out before the end of the weekend (hopefully split out and cleaner) that'll add the FB support; I have it working locally.
Ah, your blurred picture got me so excited I didn't read your website correctly!
Any hint on how you got the LCD to work? (my FB code seems to match the FB code in your patch), or am I going to have to wait until the weekend!
What else is there to do? Just to confirm, the current status is:
Kernel booting Serial port working USB working NAND reading & writing FB working
Which leaves: sound ?! Mini keyboard (PS2 right?) u-boot NAND read (& write ?) Getting PBL tool to load & run u-boot from flash DSP!!
