  • Forum Post: How do we configure the PLL on the TMS570LS series devices?

    S Tsuei
    The configuration of the main PLL and clock wrapper is controlled by two registers, PLLCTL1 (offset 0x70) and PLLCTL2 (offset 0x74) in the System module. Programming these two registers selects the operating mode, frequency, reset behavior on PLL slip or oscillator fail. . PLLCTL1 register...

  • Forum Post: What are the reset requirements?

    S Tsuei
    Power-on-reset: When either of the core (1.5V nom) or I/O (3.3V nom) supply voltage is detected out of regulation, the power on reset input pin (nPORRST) must be asserted by the external power supply monitoring circuitry for at least 1 ms. (Core supply min required and max allowed are 1.35 V and 1...

  • Forum Post: What kind of oscillator/crystal can be used?

    S Tsuei
    A few requirements apply. When using a crystal/resonator across OSCIN and OSCOUT, the resonator/crystal frequency should be within 5-20 MHz range. When using an external clock source driving OSCIN (OSCOUT unconnected) the clock signal should be toggling 0-1.5 V. Please refer to the TMS570LS series...

  • Forum Post: What are the available clock sources and domains? What registers are used to map a selected clock source for a particular domain?

    S Tsuei
    The clock sources and domains are managed by the Global Clock control Module (GCM). The clock domain output signals generated (from the selected clock source input) by the GCM are used to clock the various modules on the device. GCM also controls the enabling and disabling of the clock sources and domains...

  • Forum Post: How are error conditions handled?

    S Tsuei
    The various error conditions on the device are managed by the Error Signaling Module (ESM). The severity level of the error determines how the error is handled. The severity level is device specific and is implemented by mapping each of the device error signals to the appropriate group of error/interrupt...

    The code generation tools come with a Stack Depth Profiler. If I get your question right, then this may be able to help you. This tool (sdp470.exe) can be found in your CCS installation directory. For CCSv4 users the default installation location for the compiler tools is: \Program Files\Texas Instruments...

    John Hall
    Here is the code used for the boot code. Note: The function being called, Init_code() will be decorated in TI's COFF format as $Init_code which is what the symbol is referred to in the command linker file. Using EABI format, there is no decoration and the symbol would be Init_code in the command...

    I have a very trivial boot code[just a PLL init and checking if a valid app is present]. How can I make a jump to the App. Can some one share how you jump from boot to App.

    You can also use JTAGjet-470, JTAGjet-570 or JTAGjet-CCS from Signum Systems. They all support CCStudio 3.3 and 4.x. See: http://www.signum.com/jtagjet.htm

    The TMS570 USB Stick features an on board XDS100v2 JTAG emulator. The on board XDS100v2 is the primary solution for JTAG connectivity to enable debug and flash programming on this piece of hardware. The J1 pads on the bottom of the board that provide access to the TMS570 JTAG signals are intended for...

    The TMS570 Technical Reference Manual contains a section on the Error Signalling Module where it talks about groups and channels. There are some references to Group 2 channels 6, 8, 10 and 12 in the document. Where are the channels for each group defined? Thanks

    Jeff, I have never used an ICT tester per se so I cannot comment on how to set one up for this. Our current TMS570/470 customers either use an offline programming solution or use their own methods for programming the devices in circuit with or without their own proprietary boot code.. There are...

    Jeff, They are in the process of adding their support for the TMS570 devices which should be done in the next couple of months. As soon as they are finished and we have validated their solution, it will be added as a 3rd party tool link on the page.

  • Forum Post: Phantom interrupt vector

    The TMS570 has a phantom interrupt vector but I can find no reference in the technical reference manual as to why or when it is called. Is this vector called when there is no entry for an interrupt in the CHANMAP registers?

    Richard Burke
    We are using CCS4 and the Spectrum Digital XDS510 USB JTAG debugger. When debugging an application, the whole of flash memory is erased.

  • Forum Post: TMS570 Interrupt priorities

    Richard Burke
    It is my understanding that the TMS570 effectively has only two interrupt priorities, IRQ and FIQ. Whilst the CHANMAP mechanism provides a way to rank interrupts in priority order, this only applies when two interrupts are pending and an IRQ interrupt cannot be interrupted by a higher priority IRQ interrupt...

He was setting the PLL to have a 100MHz clock which should have a 50 for the wait value, but he was passing a value of 8. Once he corrected this value,...
