Read/Write on Memory Register

Anyone???

Hi,

Can you please explain the meaning of "version number of application". Are you asking of the silicon revision of a particular processor ?

Hi,

I have two projects, the first one is my application with some function and the second one is bootloader. The first project generates an output file .ldr, which from bootloader project I use the .ldr to write/read into flash (By doing write/read the .ldr into flash I am able to boot the flash then and run my application).

From the first project I define application/software version number as:

asm("R0 = 0x19(X);");
asm("B[0x11800014] = R0;"); // writing value 25 on register 0x11800014

The value is saved on register from application project. Then I write/read the generated .ldr file into flash from bootloader project.

From bootloader project I want to read the value (value 25 saved on register 0x11800014).

I don't know if it makes sens or not.

Hi,

This issue is already handled through private support. To avoid duplication of efforts, you can continue the discussions through private support and we will post the final resolution here if appropriate.

No, it is not.

Hi,

Apology for the long delay.

In this case you have to use permanent memory for storing the software versions, otherwise we would suggest you to look on the SSL which helps to store the .ldr file in different sector in SPI flash and boot from a selection of mapped applications. For more details on SSL Please refer the EE-374 from the below link,
