    Dual-Application Bootloader with Combinaison Project

    jiwa_284501

      Hi all,

       

      To begin i will present you that i want to do.

      For my project i need to do a dual-application bootloader. In a normal utilization when the product is started the BOOTLOADER should wait an USBFS command.

      This command asks to BOOTLOADER to JUMP in APP#0 or APP#1. When this step is done. APP#0 or APP#1 should be able to JUMP in BOOTLOADER or in the other APP#x. That why the Dual-Application Bootloader with Combinaison Project seems to be the best use case for us.

      For the moment,

      - when i am in BOOTLOADER, i receive the USB command to jump in APP#0 and i JUMP in APP#0

      - when i am in BOOTLOADER, i receive the USB command to jump in APP#1 and i JUMP but i don't know where...

      - when i am in APP#0 and i want to jump in APP#1...after the Bootloadable_Load() i re-jump in APP#0

       

      See follow the architecture of my project: ("Memory View")

      In all project, all Bootloader and Bootloadable component name are the sames.

       

      Mains code architecture:

      Compilation and Program process:

      - Compilation of BOOTLOADER Project

      - Compilation of APP#0 Project

      - Compilation of APP#1 Project

      - Run a shell to use cypelftool.exe

      - Execute command: cyelftool -M App1_1.elf App2_2.elf MultiApp.hex --flash_size 262144 --flash_row_size 256

      - Program MultiApp.hex file. (with psoc programmer)

       

      We can not use Bootloader host due to a custom USB VID/PID. (not detected by bootloader host).

      So I use a custom software to send USB frame to request a jump.

       

      For me the main issue is that i can't change the active APP parameter. I fact when i do a SetActiveApplication(APP#1), the return are 0x09 (ABANDON)

      And in fact the return of Get_ActiveApplication is always "0x0000".

       

      My Questions:

      -How jump to BOOTLOADER from APP#0 and APP#1?

      -How jump to APP#0 from APP#1 and to APP#1 from APP#0?

      -How i can be sure that my APP#1 are present when i program my firmware? (APP#0 seems to by always present)

       

      Thank's in advance.

          Hello Jimmy,

           

          (Q1) How jump to BOOTLOADER from APP#0 and APP#1?

          Bootloadable_Load();

           

          (Q2)How jump to APP#0 from APP#1 and to APP#1 from APP#0?

           

          int main(void)

          {

              uint8 runningApp;

             

              CyGlobalIntEnable; /* Enable global interrupts. */

             

              /* Initialize the in app bootloader */

              Bootloader_App_Initialize();

             

              /* store current active image in order to switch images later */

              runningApp = Bootloader_App_GetRunningAppStatus();

           

              for(;;)

              {

                  /* Ping bootloader interface for in app updates */ 

                  Bootloader_App_HostLink(1u);

                  CyDelay(2000);

                  /* Check for custom inputs here, switch the active image and reset */

                  {         

                      if (Bootloadable_MD_BTLDB_ACTIVE_0 == runningApp)

                      {

                          Bootloadable_SetActiveApplication(Bootloadable_MD_BTLDB_ACTIVE_1);

                          Bootloadable_Load();

                      }   

                      else if (Bootloadable_MD_BTLDB_ACTIVE_1 == runningApp)

                      {

           

                          Bootloadable_SetActiveApplication(Bootloadable_MD_BTLDB_ACTIVE_0);

                          Bootloadable_Load();

                      }

                      else

                      {             

           

                      }

                      CySoftwareReset();

                  }

              }

          }

           

          (Q3) How i can be sure that my APP#1 are present when i program my firmware? (APP#0 seems to by always present)

          Please make use of code in (Q2). Application will be loaded only if present.

           

          Best Regards,

          Geona Mary

            Sorry for the late response i was on vacation .

             

            I will take time to test this code and i will give a feedback after.

             

            Best Regards,

              Hi,

               

              Thank you, this code works well.

               

              I needed to add in "main.c" of the Bootloader this code because when APP#X want to jump in APP#Y the program jumps before in the Bootloader (not in app bootloader):

               

                  for(;;)

                  {            

                      if(Bootloader_GetMetadata(Bootloader_GET_BTLDB_ACTIVE,0) == 01)

                      {

                          UART_PutString("Jump in APP#0\r\n");

                          Bootloader_Exit(Bootloader_EXIT_TO_BTLDB_1);

                      }

                      else if(Bootloader_GetMetadata(Bootloader_GET_BTLDB_ACTIVE,0) == 00)

                      {

                          UART_PutString("Jump in APP#1\r\n");

                          Bootloader_Exit(Bootloader_EXIT_TO_BTLDB_2);

                      } 

                  }

               

              Best regards,

               

              Jimmy.

                Hi,i have the same question.i am using psoc5lp prototype kit and running dual app in bootloadable but bootloading function(API)does not work and gives me without sources error.

                What is my mistake?
                How can i use bootloader Launcher-Combination function?

                Can you see my project file to solve problem?

                Thanks for attention
