• Which steps are needed to get UART interrupts working on ADSP SC582 / 584 sharc core?


    I followed several advice to setup interrupts for my custom circuit board with the  ADSP SC582 and the ADSP SC584 - EZ Lite kit - it just won't work.

    For setting up the interrupts itself I considered the following explanation (https://ez.analog…

  • RE: ADSP SC582 - UART0 auto buffer DMA - DMA somehow works but UART0 THR receives wrong data

    Hi Anand Selvaraj,

    thanks for your answer.

    1. In which memory does your data reside? Is it in L1/L2/L3 memory?

    Only L1 cache is enabled.

    2. I could see that you are using ADSP-SC582. Which core(ARM/SHARC0/SHARC1) contains the UART code?

    The ARM core…


    In user-manual, I find the GPB2 can used for PTP Clock input 0. And in linux-kernel, there has "devm_clk_get(priv->device, "clk_ptp_ref");", but there is no clk_ptp_ref clock in sc58x.dtsi.

    I want to connect a signal(49MHz) to…

  • VFP Register error on SC582 with FreeRTOS


    I have a project where we use the SC582 with FreeRTOS without any additional compiler options. My problem now is that we pass a float as an argument into an function but the VFP Register is overwritten in an interrupt. 

    So for me it looks like…

    We're currently laying out a prototype PCB to take an ADSP-TS203 TigerSHARC
