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.
