Linux/TAS5805M: Need PBTL Mono 1.0 configuration /header file

Hi Andy,

Thanks for the reply and we are using the linux driver code from TI (PBTL Mono Mode 1.0) and we observed some times the device going to Sleep state without writing any I2C state commends.

do you have any suggestion please let us know.

Hi,

My Configuration is PBTL Mono 1.0.

I am using the header file generated from TI Reference "stereo_flow2_48kHz_default_coldboot_-10dB" for Linux version.

and I tried both the ways like manual configuration of the resistors using I2C commands below and through the Header files posted in the forum.

speaker-test -D hw:0,2 -t sine -r 48000 -c 2 -F S32_LE -S 5 &> /dev/null &

i2cget -f -y 0 0x2c 0x54

i2cget -f -y 0 0x2c 0x4c

i2cget -f -y 0 0x2c 0x37

i2cget -f -y 0 0x2c 0x68

i2cget -f -y 0 0x2c 0x69

i2cget -f -y 0 0x2c 0x6d

i2cget -f -y 0 0x2c 0x70

i2cget -f -y 0 0x2c 0x71

i2cget -f -y 0 0x2c 0x72

i2cget -f -y 0 0x2c 0x73

i2cget -f -y 0 0x2c 0x75

i2cget -f -y 0 0x2c 0x03

i2cget -f -y 0 0x2c 0x50

working boards had this values in I2C Read using the same configuration file:

54 = 0x00

4c = 0x30

37 = 0x09

68 = 0x03   // State Registers

69 = 0x03

6d = 0x50

70 = 0x00

71 = 0x01 / 0x05

72 = 0x00

73 = 0x00

75 = 0x38

but only few boards work this way and most of them are giving faulty register values. we suspect the header files may corrupt the configuration of chip.

I ordered the eval boards but need to check these setting to make sure I am running the correct header files into the chip.

and I don't have the PBTL Mono 1.0 header files to check if these issues are happening due to configuration files.

if you have a solution please let us know or give us the configuration files for PBTL mode that would be great.

Karthik

 

Hi Andy,

Thanks for the configuration files and can you get the header files for 48Khz in same PBTL mono 1.0 mode.
