  • Thanks Jan, that was really helpful. I think I made the silly mistake of using a USB hub so the Olimex and UART/pwr USB were both always connected, whoops. I turned off, removed the JTAG ribbon and re-applied power using only the CN2 and my program came back, as I wanted it to i.e. hard-coded into the board.

     

    Thank you for your quick and helpful comment. I'd spent hours looking around the Eclipse menus for something that seemed to be related to a 'download' option.

     

    Onwards ! image

  • Does it start if you power it up from an external power source, without the debugger attached?

  • I would be grateful for some advice to see me over an initial hurdle, mainly because I'm a bit of a novice at ARM and Eclipse: I've installed the ARM Cortex Toolchain from Maxim and are therefore using their Eclipse version and the Olimex unit to debug or run the code on the MAX32650. Currently I seem to be able to make things happen but when I remove power and power up again my program doesn't start up. If there a way to download th compiled image (which I think is the ELF file) directly to the MAX32650's FLASH ?

     

    And in return, a little snippet of what I'm up to as part of my roadtest:

  • For info: my MAX32650-EVKIT has arrived safely, thank you

  • The GPIO supply rail can be configured as VDDIOH (3V3). By default these are using VDDIO (1V8) supply.

    Here is the simple function to configured any GPIO to use VDDIOH supply instead of VDDIO. (Certains pin cannot be configure to use VDDIOH refer to reference manual: section 5.3 GPIO on page 99)

     

    void GPIO_EN_VDDIOH(const gpio_cfg_t *cfg, uint8_t enable){
            mxc_gpio_regs_t *gpio = MXC_GPIO_GET_GPIO(cfg->port);
            if (enable == 1) {
                 gpio->vssel |= cfg->mask;
            }
            else {
                 gpio->vssel &= ~cfg->mask;
            }
    }

     

    The schematic shown in datasheet is of REV 2 not REV 3. Rev 3 has different PIN assignment and JP14 functionality. Consult mxc_pin.c file available at "C:\Maxim\Firmware\MAX32650\Libraries\MAX32650PeriphDriver\Source" location before configuring any GPIO to use VDDIOH instead of VDDIO. Because onboard ICs are using 1V8 supply and applying 3V3 to wrong GPIO can damage any of these ICs.

     

    LCD is using 3V3 supply and when using LCD all the GPIO assigned to LCD are configured to use VDDIOH. Changing the configuration of these GPIO to default VDDIO (1V8) can also damage the MCU GPIO.

     

    int SYS_CLCD_Init(const sys_cfg_clcd_t* sys_cfg_clcd_t);     // Function available at C:\Maxim\Firmware\MAX32650\Libraries\MAX32650PeriphDriver\Source\mxc_sys.c

  • , a real jtag device may be able to recover - or a person that knows how to script the on-board debugger.

    My code had the guards that you describe but a bug introduced by myself caused it to not get called. Such is life.

  • I suppose if anyone were to try a similar thing, perhaps add a delay after starting up for at least a few seconds so you can access the programming mode/bootloader before it gets stuck in a sleep mode all the time?

     

    I wonder if the Maxim chips have a way to recover - from memory, the Atmel/Microchip ATmega series have "high voltage" programming modes which blow through most misconfigurations. That being said, I suppose some chips do have one-time programmable eFuses which could be destroyed by a mistake as well ...

     

    I guess the key to all of this is that it's unintentional. I'm just surprised a reviewer tasked with the job of reviewing would intentionally choose to break it ... that's breaking new ground!

  • I made a program to loop through the sleep modes - to measure the power usage. But because of a bug it spent less than 1% of the time in a mode where the debugger would be able to address the IC.

    It was impossible to reprogram the IC after that with the on-board debugger. I tried by tactically pressing the debug button in the IDE and the reset on the board. Never recovered.

    I purchased a few new controllers (these are very cheap) and placed a new one on the kit.

     

    edit - correction: I purchased a new evaluation kit, and got free samples from Maxim to fix my board.

  • I hope I do not do this... What led up to this unfortunate circumstance.

    I wonder if we need to have a gallery of worst/most amusing RoadTest application responses? Seriously, I never thought of doing that.

    Best of luck to all RoadTesters - hopefully nothing will be broken as a result of the RoadTest ...

     

    - Gough

    In my case it would be reality though. I broke - and had to fix - the Infineon differential driver, a TI tiny switching IC and the Maxim MAX32660 evaluation kit image.

    Also broke my electronic load a few times - one time all ICs up to the I2C isolator got destroyed, and I damaged the GaN FET in another TI evaluation design

     

    Except for the Infineon (damaging it was part of the evaluation process) all were not intentional. But also not unexpected.

    The odd one out is th MAX32660 that didn't die from electronics abuse, but got bricked in an unrecoverable state when I had a software bug while testing the sleep modes.
