Hi,

I want to store 40 bytes of information on flash during run time, which can be used when there is power recycle.

From  http://www.ti.com/lit/ug/swru393d/swru393d.pdf 

status = osal_snv_read(0x80,10, (uint8_t *)write_buffer );

status = osal_snv_write(0x80,10, (uint8_t *)write_buffer );

Part Number:TMS570LS3137

Tool/software: Code Composer Studio

hello

right now i am trying to impliment the bootloader and application project on the tms570HDK,both the bootloader and the app use UCOS-II and tftp (lwip).

most scenario you talked about are like this :

(e2e.ti.com/.../225447)

  _c_int00     ;0x00   Bootloader reset
         b #0x7ff8    ;0x04   undefined_instruction, branch to application
         b #0x7ff8    ;0x08   software_interrupt, branch to application
         b #0x7ff8    ;0x0C   prefetch_abort, branch to application
         b #0x7ff8    ;0x10   data_abort, branch to application
        b #0x7ff8 ; reserved, branch to application
        ldr pc,[pc,#-0x1b0]        ;0x18
        ldr pc,[pc,#-0x1b0]        ;0x1C

The application vector table at the address 0x8000 should look as follows.

         b   _c_int00     ;0x00   application reset
         b  _undef_ISR;  0x04 undefined_instruction
         b  _swi_ISR    ;0x08   software_interrupt 
         b  _prefetch_abort_ISR    ;0x0C   prefetch_abort 
         b  _data_abort_ISR    ;0x10   data_abort
         b  _reserved_ISR ; reserved
         ldr pc,[pc,#-0x1b0]        ;0x18
         ldr pc,[pc,#-0x1b0]        ;0x1C

 in all these cases ,the irq using the vector mode,and in the boot proj, the udef ,abort , swi have no ISR,,they just jump to the app‘s ISR.

so is the spna236,

but for the ucos project, the IRQ have to use index mode (legacy arm7 mode ) ，and all the exceptions have to be down in the bootloader .

can you give me some advice?

or if the sharing vectors in sram method described in spna236 works ,can you give me some specific suggestions about how to do in the app?

i am stucking here for a month ,realy need your help!

thank you !

How does this LED calibration State machine work for LED1 (IR LED) and LED2 (Red LED)?

Also, does each calibration algorithm works the same? I was curious whether there are some common parts of the both "calibrationLED1" and "calibrationLED2" function.

Lastly, how did those min/max/threshold/hysteresis values calculated?

Hello,

On concerto control card i am using some of the GPIO as output and trying to toggle them in 1 sec timer interrupt for testing purpose. 

int count=0;
__interrupt void cpu_timer0_isr(void)

{

PieCtrlRegs.PIEACK.all = PIEACK_GROUP1;

count++;
if(count==1)
{

// GPIO high 

GpioG1DataRegs.GPADAT.bit.GPIO23      =1;

GpioG1DataRegs.GPADAT.bit.GPIO25      =1;

GpioG1DataRegs.GPBDAT.bit.GPIO42      =1;

GpioG1DataRegs.GPBDAT.bit.GPIO45      =1;

GpioG1DataRegs.GPBDAT.bit.GPIO46      =1;

}

else if(count == 2)

{

// GPIO Low 

GpioG1DataRegs.GPADAT.bit.GPIO23      =0;

GpioG1DataRegs.GPADAT.bit.GPIO25      =0;

GpioG1DataRegs.GPBDAT.bit.GPIO42      =0;

GpioG1DataRegs.GPBDAT.bit.GPIO45      =0;

GpioG1DataRegs.GPBDAT.bit.GPIO46      =0;

count =0;

}

for all above GPIO, i have done configuration of DIR and Mux registers  properly. But still GPIO's are not getting toggled.

Also i used one more method for toggling GPIO, that is as below

int count=0;
__interrupt void cpu_timer0_isr(void)

{

PieCtrlRegs.PIEACK.all = PIEACK_GROUP1;

GpioG1DataRegs.GPATOGGLE.bit.GPIO23      =1;

GpioG1DataRegs.GPATOGGLE.bit.GPIO25    =1;

GpioG1DataRegs.GPBTOGGLE.bit.GPIO42      =1;

GpioG1DataRegs.GPBTOGGLE.bit.GPIO45      =1;

GpioG1DataRegs.GPBTOGGLE.bit.GPIO46     =1;

}

In this method, GPIO23 and GPIO25 are getting toggled. but others not. Also i observed while debugging that, on register level these bits are not getting toggle.

Please help me in this.

Hi,

I am looking for example code to use osal_snv_read and osal_snv_write operation.  How can I use these function in Project Zero App code. I have read BLE Developer's guide - Section 3.10.3. When I implemented these function it returns invalid parameters.

I have read couple of forums but still it does not offer any clarity.

My questions are:

1.  Do I need to to call osal_snv_init function from APP? If yes, from where should I call it? As per my understanding this function is already called from BLE Stack.
2. OSAL_SNV = 1 is set in BLE Stack (BLE SDK 2.2.1.18). It was already 1 , but I reprogrammed ble stack.
3. Is there any particular order of calling osal_snv_read and osal_snv_write operation?
4. status = osal_snv_write(0x80,10, (uint8_t *)write_buffer )  , Is this function call correct?
5. It mentions that these operations are costly, How much time do I need to provide before calling any other functions?
6. Can I call these functions from task functions?
7. I only need to store 100 bytes of information once during configuration of device. Can I use osal read and write function or do I need something else

Thanks

Hi there,

We are using CC2650 on one of our device.

I dont have a CC debugger currently, so I am using CC2650 launchpad to program. 

But the XDS110 debugger is not able to recognize my device.

I have tried almost everything on the hardware side, such as putting external Pull-up resistors on JTAG pins , using TCK, TMS combination only etc. but no success.

If anyone else has faced similar issue before, please help us.

Any assistance would be appreciated.

Thanks.

Hello,

I am using some memory of the flash as a filesystem and storing some data in file system to use it in run time. Following are the cases which are erasing or corrupting the flashed firmware and I need to flash the firmware again.

1. when I delete the file from the filesystem (happen sometimes).
2. when I copy the more data in filesystem then its size allocated (happen always).

Please provide solution to prevent this situation for above cases.

Part Number:TMS320F28377D

Hi.
I write the C2000 project, running on TMS320F2837xD. The project was developed from blinky_cpu1 example.  I run the program via JTAG from RAM, measure duration of calculations and then change configuration to FLASH, because the application finally will be run from FLASH. The duration takes much more time (6-8 times more!) I looked for the information how to load to FLASH and run from RAM and was confused. I have several questions:
1. Can I change the project to the DSP/BIOS configuration? May be it will be the easiest way to solve the problem?
2. In order to copy functions to the section "ramfuncs" what exactly should I do? In the linker command file or/and in the code. I use 2837xD_FLASH_lnk_cpu1.cmd file. My code is written in C/C++.
3. If functions call other functions, all of them should be moved to RAM or linker will do it automatically?
4. I need examples which matching to my microcontroller TMS320F2837xD.
Thanks.

Part Number:LMP8646

I wanted to use this IC as a current sensor so just for preliminary testing I used a sense resistor(Rsesne) of 0.5 ohms and gain resistance (Rg) of value 49.9K. The supply voltage given to the IC was 12V and the common mode voltage (Vcm) to the input terminals was 6V. I passed a current of 0.4 A. From this I calculated that the output voltage (Vout) would be 1.996 V however I was getting an output voltage of just 0.13 V.

I tried changing the currents to different values however I never got the expected value. The value that I got was always less than what I was expecting.

Part Number:MSP430FR5994

Tool/software: Code Composer Studio

I am trying to generate multiple frequencies from timer interrupts (to flash LEDs at different rates, etc.) using Multiple Time Bases similar to the two links below.

www.ti.com/.../slaa513a.pdf
e2e.ti.com/.../1165370

However, when I try to set "TA0CCTL3" and "TA0CCR3" (and 4/5/6, not shown here) I get the following errors.

"../main.c", line 263: error #20: identifier "TA0CCTL3" is undefined
"../main.c", line 264: error #20: identifier "TA0CCR3" is undefined

With the MSP430FR5994 (on the MSP-EXP430FR5994 Development Kit) I should be able to define up to TA0CCR6. Any suggestions why this is not working?

Here is my code to configure the timers. I also use #include <msp430.h> in the code.

    TA0CTL |= TASSEL_1;             // Use ACLK as source
    TA0CTL |= ID_0;                 // Divide clock by 1
    TA0CTL |= MC_2;                 // Use CONTINUOUS mode timer
    TA0CTL |= TACLR;                // Clear timer

    TA0CCTL0 |= CCIE;               // Enable Interrupt on Timer
    TA0CCR0 = 5000;                 // Number of cycles in the timer

    TA0CCTL1 |= CCIE;               // Enable Interrupt on Timer
    TA0CCR1 = 10000;                // Number of cycles in the timer

    TA0CCTL2 |= CCIE;               // Enable Interrupt on Timer
    TA0CCR2 = 15000;                // Number of cycles in the timer

/*
These two lines create errors - TA0CCTL3 and TA0CCR3 are undefined.
See Table 25-8 in slau367o.pdf - should be able to define 7 counters.
*/

    TA0CCTL3 |= CCIE;               // Enable Interrupt on Timer
    TA0CCR3 = 20000;  		    // Number of cycles in the timer

    TA0IV = 0x0000;                 // Clear the interrupt flag

I have move project from IAR 7.50 to IAR 7.80 for using simplelink_cc13x0_sdk_1_30_00_06.

In the original project I have const argument that get values before staring the run (before the main(). The address point to is set in the .icf to the  ROM section follow:

define symbol __ICFEDIT_region_ROM_start__ = 0x00000000;
define symbol __ICFEDIT_region_ROM_end__ = 0x0001FFFF;

and the variable itself declare as follow:

__no_init const TSProductInfo PRODUCT_INFO @ (0x20000 - 4096*3) = 
{
APP_VERSION,
APP_REVISION,
APP_BUILD,
APP_DAY,
APP_MONTH,
APP_CENTURY,
APP_YEAR
};

In the main.h

extern __no_init const TSProductInfo PRODUCT_INFO;

and every file need it get #include "main.h"

It work O.K. but when I move to IAR7.80 I get 2 problem with it.

1. It doesn't allow me to put predefined values inside before the run.

2. I get error from the file using it as "Error[Li005]: no definition for "PRODUCT_INFO" ....." also they have the #include and if I ask for its define it jump to its deceleration.

Is it something change in the IAR environment or I have declare it incorrect?
