    Mughees Chohan
    The current documentation for DM8148 is has many errors. Like it says that USB_CM_DEFAULT_CLK_CTL register is at location 0x4740054c when in fact it is at 0x47400558 similar to DM8168. When will be the new documentation available?

    Hi, I test VpsUtils_queGet() in hdvpss_01_00_01_37_patched\packages\ti\psp\vps\common\src\vpsutils_que.c. I found the handle->flags is always zero. Is it always zeros so it doesn't post semaphore to unblock, so the frameList->numFrames =0 ? if ( handle->flags & VPSUTILS_QUE_FLAG_BLOCK_QUE_PUT...

    Hi Sujith, If it is always zero, it's OK? Now I don't need to use 5158. And I want capture 1080P 60, 16bits-422, and SINGLE_CH_NON_MUX_EMBEDDED_SYNC. I need to change the driver of capture?
