Hello,I am wondering what could be the best way to write a device tree that sets the STM32MP1 as SAI SLAVE with a CODEC also running as SAI slave. The HW design I am studying has the following specs:1) STM32MP1 with ALSA and one SAI interface.2) A co...
Hello everyone, I am trying to debug a custom board with STM32MP151 with WM8988 connected with SAI2, the connection is just as STM32MP15x-DK with except that there is no I2S to HDMI. The device tree configuration is a mimic of STM32MP15xx-dkx.dtsi. ...
I generated the device tree for the STM32MP135-DK to include the tlv320aic31xx audio codec connected to the sai1a port, but during the boot I get the following errors. [ 90.094282] st,stm32-sai 4400a000.sai: missing x8k parent clock: -2[ 90.155023]...
Hello everyone,I am trying to replicate this approach to integrate STM32MP1 with an external audio codec. The issue I am facing is that the sub-block SAI-A is generating the bitclock (SCK), while I need it to receive it from the external audio codec....
I have several questions first one is what is the max clock for I2C, minimum is pointed at this sheet but what is the max?Again for the same sheet for the LCD-TFT controller, I will be using 1.8V LVDS display so fclk frequency will be 45 MHz max righ...
Hi,We are using stm32mp157a in our custom board.We are configured SAI for Cortex M in cubemx.But we are unable to get dma interrupt and data through DMA. you can see my code flow below.In main.we are calling below functions.int main(){ MX_DMA_Ini...
SAI2 Block A configured as a MasterTX and works. Fs configured for 48KHz, bit clock configured as 64*Fs and MCLK as 256*MCLK. I've verified these signals are sent to the audio codec which is configured as a slave (receives MCLK, SCLK, LRCLK (Fs)). Th...
If I configure SAI 2 in cubeMX I get a greyed out option that the synchronous slave is not available unless I have one SAI as master, but I have set SAI A as master (or master with master clock out). So what am I doing wrong?It doesn't matter if I co...
