Hi Guys, I am working on SPC584B-DISP Board.In this board i need bootloader option so that i am try to use example SPC584Bxx_RLA Bootloader Test Application for Discovery 2 .In this example download code from serial UART .

[Ravi S]

In this I can able to download bin file from UART next step jump to app in this step not working if any one have idea please help .......

Thanks advance ...

Hello,

your problem 2 is known:

So you have to use option Copy in RAM

(because 0xFC0000 and 0x1000000 are in same partition0)

Then you enter into problem 1 ...

you write binary in flash at 0x100000 but it does not start

Did you check your application program to generate this binary was configure to run from 0x1000000?

Your bootloader must be in Copy in RAM 0x00FC0000

Your application program must be in Execute from Flash 0x01000000

Hi Olivier sir,

Thanks for your replay i will check and update ASAP.

But what is the main difference between Load in RAM and Copy in RAM if you have any documents pls share with me.

Thanks regards

Hello Sir,

the firmware updater documentation can be found in your project here:

I have that document sir .As per this document only i am doing but no result.

[Ravi S]

Hi sir,

As per your suggestion I done following thinks

1.Load the bootloader code into address 0x00FC0000 using Copy in RAM method.

2.Using external MCU send following data to SPC584B-DISP board.

Step 1:-

External MCU Send Password(FE ED FA CE CA FE BE EF) to SPC5 MCU. SPC5 MCU once receive password and compare and response(00 00 00 01 CA FE BE EF) ack is OK.

Step 2:-

External MCU Send Bin file size(00 00 00 00 00 00 4F 38) to SPC5 MCU.SPC5 MCU echo the bin size to External MCU OK.

Step 3.

External MCU Send bin file 8 byte at a time .SPC5 MCU receive data and write into flash(0x01000000) and echo response to External MCU OK.

Step 4:-

Final step Jump to app not Happening.

If I make any mistake please let me know.

Thanks

Hello Sir,

may be you forgot this step?

Step0:

When you generate your application binary, you must generate it to run from flash at address 0x01000000:

I done this steps sir not forgot .

I attached the screenshot for your for your reference.

[ODOUV.1]

Thank you for your confirmation,

Looking deeper in document and in code, It seems to be the normal behavior.

It is explained in document in step3:

MCU must be restarted after programming to enter into new program, because the jump to new program is not called at end of programming.

Hi sir ,

Thanks for your replay.

Once all code downloaded .Power OFF/ON the Board or press reset button .I tried both method .After restart bootloader code run and stopped .My app code not running.

I attached the status LED screenshot for your reference.

 

Once all bin file write into flash .Then I restart MCU .After restart Led 1 ON for 5 sec the Both the LEDs ON always .Nothing happened .

[ODOUV.1]

I wonder if you are not confused by wrong LED status

because on SPC584B, the LEDs are not connected from PADs to GND,

but there are connected from PADs to VDD.

So by default, when the program set the PAD to level High, the LED is OFF

and when the program set the PAD to level Low, the LED is ON

LED1 is on PortF8

LED2 is on PortF9

You have to invert the configuration for both LED1 and LED2:

Would you please check that in Board Initialization -> IO settings ?

BRs,

-Olivier

[Ravi S]

Hi Sir,

I checked the Board Initialization LED configure correct only.

If LED status wrong also app code will run right .My app code is simple program ON/OFF 3 LED s one by one. I tested this app code using UDE STK 2021 tool to flash the code and reset the board its work fine ,

But UART bootloader mode only not running I try this around 1 week . But not able to complete .

If u have any ide pls share me .

Thanks regards

Sir,

I just sent you 3 files:

1) SPC584Bxx_RLA PIT Test Application for Discovery 2.zip

in the build directory, you will find application program binary out.bin to flash at address 0x1000000

Then, when you switch ON your board, you should see :

LED1 blinking every 1 sec,

LED2 blinking every 2 sec,

LED3 blinking every 4 sec.

2) SPC584Bxx_RLA Bootloader Test Application for Discovery 2.zip

in the build directory, you will find bootloader program binary out.bin to flash at address 0xFC0000

Then, when you switch ON your board, you should see :

only LED1 set ON for 5 sec

then all LEDs OFF

3) spc5loader.zip

This is the PC tool to use with bootloader

flash the bootloader binary from 2)

connect an USB cable from your PC to the MCU Dicsovery2 USB

launch the spc5loader tool and configure it with good COM and the application binary out.bin from 1)

then switch ON the board

only LED1 should be ON

and clicl on Program within 5 sec

if load works correctly, at the end you should have LED1 ON and LED2 ON

then reboot the MCU, you should see LED1 for 5 sec

and then the 3 LEDs should blink ever 1sec/2sec/4sec

BRs,

[jmary]

Olivier, would you please send the files also to me.

[Ravi S]

HI Sir ,

Thanks for your replay .

As per your last replay i done following things please check once .

Step 1.

Restart MCU and Using spc5loader load the SPC584Bxx_RLA Bootloader Test Application for Discovery 2 out.bin file.

Step 2:-

Restart MCU. Using spc5loader load the SPC584Bxx_RLA PIT Test Application for Discovery 2 out.bin file.

Step3:-

After Program flash completed .Restart MCU.

First 5 sec LED 1 ON .& LED 2 OFF

After 5 Sec LED 1 & 2 OFF nothing happened.

I attached the pictures for your reference. One more thing I am using your bootloader and your app file only for flash and testing.

1.After restart MCU.First 5 sec.2.After 5 sec all LED OFF nothing happened.

Still program load but not executed sir.

Thanks & Regards

Hello Ravi,

Sorry but you did not follow what I asked.

Let's redo step by step.

Step 1) SPC584Bxx_RLA PIT Test Application for Discovery 2.zip

****Do not try to regenerate or rebuild, just unzip and use like this.****

in the build directory, you will find application program binary out.bin to flash at address 0x1000000

****Do not use spc5loader, use your normal flasher tool ****

****Remark we do not flash Bootloader program but PIT program here****

****Before to flask PIT program at 0x1000000, please erase all your flash partitions ****

Then, when you switch ON your board, you should see :

LED1 blinking every 1 sec,

LED2 blinking every 2 sec,

LED3 blinking every 4 sec.

Please do this Step 1 exactly like this.

I flashed this PIT binary using PLS on my SPC584B-DISP board and it works (3 LEDS are blinking).

Tell me what happens on your side.

Best regards,

-Olivier
