  • Forum Post: What are the CPU speed to execute code in flash for the F280x devices before the device is initialized?

    Yanming35051
    Champs, Refer to datasheet and user guide of C28x, the flash pipeline mode is not active, flash paged/random read wait states need 15 wait states and a total of 16 sysclock cycles per access the flash code/data after device reset or power up. There are serveral question on these. 1. What are the...

    Magnus Wohlfart
    Champs, I have a customer whose program is only running normally, when he doesn't use the "DELAY_US" function in the "DSP2833x_Adc.c" He would like to use the "DELAY_US" function to wait for e.g. 20us. When running and debugging from RAM there is no problem...

    Adam Vasicek
    Hi, I would like to save a few words of user settings in the internal flash of TMS320F2808 DSC. Also the program itself is running mainly from the internal flash as there is no external memory of any kind connected. Are there any other ways of achieving this apart from using Flash API Library ? (Which...

    Davor
    The flash programmer "knows" that there are initialized sections placed in RAM but cannot "know" if your code is making sure that these sections are initialized - hence a warning. Does you application run from flash, after you reset the CPU?

    johannes Sorry, I've never seen that error message. For the #pragma, please read spru514c.pdf, Section 6.9.2. It seems there may be a problem with my eZdsp f28335 board. I used Code Composer Studio to fill address 0x200000 with zeros. WhenI read back the memory, it was filled with 8s. I manually...

    Tim Love
    Tranz, The software appears to work with the PC to 28x connection just not with the micro. You should go about this by a debug approach to establish 28x to 28x communication before going to the non-28x support. The app-report details the procedure required for 28x to 28x communication. Regards...

    Hi, I have reached a point in my project where a version running from flash is required.

    Trying ‘Depletion Recovery’ (button in the Operation window) will help if the flash is in over-erase condition. Probably, the flash is permanently locked. That is all CSM locations are now 0x0000. This can happen if the erase operation is terminated (reset or power-down) before completion...

    Gaston, All of the examples included in the Header Files package are configured for boot to RAM option (with the exception of the flash example). This allows for quick and efficient evaluation for each peripheral. The flash example can be used as a template to convert the rest of the projects. There...

    You get this error while programming the flash, correct? The F28335 flash API file (FlashAPIInterface28335V1_01.out) is installed in the following folder (if you have allowed the default installation); C:\CCStudio_v3.3\plugins\Flash28xx\Algorithms\28335 When you run the CCS's On-Chip Flash...

    old_cow_yellow But I know that you cannot jump very far. You may want to try branch instead of jump. old_cow_yellow is correct, a JMP instruction uses a 10-bit signed offset in the opcode which will be relative to the current PC. Therefore, you get a -511 to +512 word relative to the PC. The...

    You don't need to go through this. Let's assume you have written a table of data, for example, into flash at a particular location. If you have a label associated with that table, then your code can reference that data in the table by the label itself. driesione 2. Can somebody also explain...

    The below is from the MSP430 code examples for the MSP320F20xx devices found here . SLAC080 I modified it to add a constant table. Because this is declared as a constant, it will be added to the .const section which in the standard linker command file will be allocated to Flash memory. #include <msp430x20x3...
