Hello, i'm having some trouble building a new custom cape for BBB which has audio codec (TLV320AIC3104) and bluetooth audio (CC2564MODA) - maybe someone that is experienced in MCASP can help?
First of all, the only solution i see is to use MCASP0 for AUDIO and MCASP1 for BLUETOOTH AUDIO. I don't think you can connect both chips to MCASP0? When wiring up the ICs, i run into a serious PIN collision conflict: *TLV320AIC3104* Codec PIN BBB PIN BBB PIN Name Signal MCLK P9_25 GPIO3_21 mcasp0_ahclkx BCLK P9_31 SPI1_SCLK mcasp0_aclkx WCLK P9_29 SPI1_D0 mcasp0_fsx DIN P9_28 SPI1_CS0 mcasp0_axr2 DOUT P9_30 SPI1_D1 mcasp0_axr0 *CC2564MODA* Codec PIN BBB PIN BBB PIN Name Signal BCLK P9_42B GPIO3_18 mcasp1_aclkx WCLK P9_27 GPIO3_19 mcasp1_fsx DIN P9_41B GPIO3_20 mcasp1_axr0 DOUT P9_25 GPIO3_21 mcasp1_axr1 Unfortunately using another mcasp1_axr instead of axr1 is impossible (MII block most PINs), also muxing mcasp0_ahclkx to another PIN is impossible because of my design (LCD PINs block this way). In some audio cape schematics, MCLK of TLV320AIC3104 is not even connected to BBB header but is connected directly to 12MHz Oscillator. *My question is, do i really have to connect MCLK <-> mcasp0_ahclkx to make TLV320 work on BBB or can i use 12MHz Oscillator <-> MCLK instead? Which way is better? What might have to be changed in software if using ext. Oscillator?* Thank you very much!!
