I have GT202 module on one of Our Board. I am using the Host driver supplied by Qualcomm to talk to the Wifi Controller. We have made changes to the SPI Driver. I am able to talk to the chip and write into the internal registers such as ATH_SPI_CONFIG_REG (0x400) , SPI_INTR_ENABLE_REG and other registers.. as part of the hcd_init.
But when i start the communication with the chip Via Driver_Bootcomm, We need to read the hi_ref_clk from the Controller. When i initiate the commincation i see the return value is not 26000000 or 40000000.
Anyone faced the similar issue. Any Inputs on this will be appreciated
Thanks
I am seeing the exact same behavior on custom hardware. I have measured the crystal frequency and it is solid 40 MHz. Has anyone found a root cause or solution to this issue?
Thanks.
