  • TDA4AH-Q1: LPDDR4 Fails to boot at 1866MHz Clock speed

    Part Number: TDA4AH-Q1 Other Parts Discussed in Thread: TDA4VM Tool/software: At 1866MHz Clock Speed the device fails to boot and gets stuck at the uboot prompt after "I/TC: Primary CPU switching to normal world boot". This board has already successfully…

  • TDA4AH-Q1: 2 PHY's different clock one Serdes

    TI Thinks Resolved
    Part Number: TDA4AH-Q1 Is it possible to use two SGMII PHYS simultaneously connected to a single SERDES say SERDES4, but those have different bit rates (say 1Gb/s and 100Mb./s or 1Gb/s and 2.5Gb/s). In other words, is it possible to communicate to both…

  • TDA4AH-Q1: ADC Sampling frequency

    Part Number: TDA4AH-Q1 Other Parts Discussed in Thread: TDA4VM Hi TI, The TDA4VM and TDA4AH TRM documents mention a 60 MHz SMPL_CLK for ADC module(s) and it seems to be a constant value. Is there a way to change (actually to lower) the sampling…

  • TDA4AH-Q1: MMCSD v2 probable typos in MMCSD_switch_eMMC_mode

    Resolved
    Part Number: TDA4AH-Q1 Hi, In PROCESSOR-SDK-RTOS-J784S4 version 09.00.01.01 (but most likely also applicable to the recently released version 09.01.00.06 and the git tree linked below), the MMCSD LLD has what I think is most likely a copy-paste typo…
