  • RE: AM5749: AM5749: GPMC setting for connect FPGA is not correct on AM5749 custom board.

    Closing this thread.

  • RE: AM5749: Early boot problem (SPL/ MLO)

    Adding to Keerthy's response... 0xC is the vector for CPU abort. It has nothing to do with PRUSS1_CFG_PRUSS_GPCFG1. You may have loaded some binary with those symbols at the address. What most likely happened was something wrong in your code, for example…

  • AM5749: DSP firmware loaded to L2SRAM segment by remoteproc

    Part Number: AM5749 Hello, I'm trying to port a c66 DSP firmware initially developed as baremetal application (without TI-RTOS) and not compatible with a running Linux OS on the ARM core. This firmware is based on a TI demo where all the board support…

  • RE: AM5749: PCIe: PCIe scan may fail on PCIe_SS2 when PCIe_SS1 and PCIe_SS2 are in single line mode.

    jian35385 said: Also once of my colleagues asked if you are using common refclk architecture, as we have seen similar link issues solved by common refclk. The refclk is provided by an PI6C557-05LE device. CLK0 of PI6C557-05LE is connected to LJCB_CLK of…

  • AM5749: GPMC setting for connect FPGA is not correct on AM5749 custom board.

    Part Number: AM5749 Hi Dears. I have a problem to setting the GPMC using dts file descriptions. I'm using SDK-linux-am57xx-evm-08_02_01_00 and SD-card booting. I modify dra7.dtsi and am574x-idk.dts files as like below. ===== dra7.dtsi ===== /* OCP2SCP1…

  • AM5749: DDR3 ECC hardware layout question

    Part Number: AM5749 Hi TI Team: We refer to the AM574x IDK datasheet and are going to use ECC on DDR3 Can TI team help us to confirm whether this AM5749 hardware circuit can working with it? Best regards ti_obc_ddr3_ecc.pdf

  • RE: AM5749: gptimer issue with a periodic event from a DSP firmware

    Resolved
    Hi Suman, Using no-idle mode fixed the gptimer instability. I hope this thread could help someone else with the default mode force-idle. I'm closing this thread. Best regards, Romain

  • AM5749: Back-to-back read issue

    Part Number: AM5749 Hello, I interfaced an FPGA to the SoC via GPMC. The retained configuration is: Asynchronous 16 bits and CYCLE2CYCLE = 0 Despite this, I observe a very long pause between two consecutive readings. The registers content is as below…

  • RE: AM5749: GPMC read issue, won't read

    Hi , Thanks for your answer, I've check my pinmux but I don't see anything in the sysconfig files (attached). all seem good to me. Clocks are OK, all GPMC pins are in default mode which is what I want (?), is there something that I didn't saw?…

  • RE: AM5749: AM574x Custom board kernel failed to boot. Any hint on booting Log.

    Resolved
    Hi, khoosen Yu said: Booting Error-20220925.txt Is this the complete logs? Does it ever come out of the loop and proceed further? khoosen Yu said: After this modification custom board boots more(?) time. :) I am little confused with the statement here.…
