PIC32MX Bootloader issue (Not Enough ROM Space Error)

[rb15780]

Hi,

Please help me regarding the issue in creating Mikroebootloader Project in PIC32 C compiler.
There is an example of PIC32 for PIC32MX795F512L HID Bootloader, Whenever i change Device from PIC32MX795F512L to any of PIC32MX7 device then it gives error of "There is not enough ROM space" and this error never gone after reselecting PIC32MX795F512L.

I need HID Bootloader for PIC32MX570F512H Device, Please provide me its HEX file or resolve this issue.

Thanks,
Ricky

Hi Ricky,

I've reproduced the same issue, and I have located a few problems.
Unfortunately, I do not have this specific MCU to test it, but I have managed to compile the project.

Firstly, I noticed that the ROM addresses from the .mlk file are wrong. Press Ctrl+Alt+M to open the .mlk file and set ROM max address to 0x1D07FFFF as below:

Code: Select all

<ROM>
        <MIN_ADDR>0x1D000000</MIN_ADDR>
        <MAX_ADDR>0x1D07FFFF</MAX_ADDR>
</ROM>

Also, the __BOOT_FLASH_SIZE constant from the MCU defs file is wrong. Please press Ctrl+Alt+D to open the definitions file and search for __BOOT_FLASH_SIZE constant and set it to 0x00000BF0.

Code: Select all

const unsigned long __BOOT_FLASH_SIZE = 0x00000BF0;

Then you need to set an EBASE address in the Edit Project Window. Press Ctrl+Shift+E and set EBASE to 0x9FC00000 or 0xBFC00000.

After that, please set the BOOTLOADER_SIZE constant from the Config.c file as described in the comments, and finally you should be able to compile the project.

Also, I suggest you take a look at the following forum posts:

I apologize for the inconvenience caused by this, I will forward this to our developers.

Kind regards,
