Problems migration mqx3.7 to mqx4.0

[feraro]

Hello.

I have a project created with MQX 3.7 and CW10.5  and working properly.

I'm trying to start a new project based on this, but with MQX 4.0.2
I have the following problem, when I try to erase the flash memory:

    error_code = _io_ioctl (flash_hdl, FLASH_IOCTL_ERASE_CHIP, NULL);

the program jumps to _int_kernel_isr

The complete code is:

   // Open the flash device

    flash_hdl = flash_open(FLASH_NAME);

    // Enable sector cache

   _io_ioctl(flash_hdl, FLASH_IOCTL_ENABLE_SECTOR_CACHE, NULL);

    _io_ioctl(flash_hdl, IO_IOCTL_DEVICE_IDENTIFY, &ident_arr[0]);

   // Get base address

   error_code = ioctl(flash_hdl, FLASH_IOCTL_GET_BASE_ADDRESS, &base_addr);

   error_code = ioctl(flash_hdl, FLASH_IOCTL_GET_BLOCK_MAP,(uint_32 _PTR_)&info_ptr);     

   // Erase all the flash

   error_code = _io_ioctl(flash_hdl, FLASH_IOCTL_ERASE_CHIP, NULL);

Someone can help me?.

Thank you very much.

Hi Fernando,

Are you running the code from flash?  If yes you cannot erase the flash you are running out of.

Have you reviewed the MQX4.0.2\mqx\examples\flashx project?

I have not compared the MQX3.7 to MQX4.0.2.

I have verified that the MQX4/0/2\mqx\examples\flashx is working with TWR-K60N512,

Regards,

David

Hi Fernando,

Which chip are you using?

Hi Kevin.

Is the internal flash MK60DN512 own.
