Look up the external flash memory region fail #848

Closed lgl88911 closed 4 years ago

lgl88911 commented 4 years ago

After 0.24, get_region_by_name be remove from MemoryMap, override the flash algorithm for an external flash memory can't work. Is there an alternative method available

def will_connect():
    # Look up the external flash memory region.
    extFlash = target.memory_map.get_region_by_name("flexspi")

    # Set the path to an .FLM flash algorithm.
    extFlash.flm = "MIMXRT105x_QuadSPI_4KB_SEC.FLM"

Apologies that you were using the API, and that I forgot to update the example! get_region_by_name() was replaced with a more general get_first_matching_region() method. It takes keyword arguments that match against any of the region attributes, including name.

So you'd use it like this:

def will_connect():
    # Look up the external flash memory region.
    extFlash = target.memory_map.get_first_matching_region(name="flexspi")

    # Set the path to an .FLM flash algorithm.
    extFlash.flm = "MIMXRT105x_QuadSPI_4KB_SEC.FLM"

The example code in user_script.md is fixed in #849.

@flit Thanks for your reply, "Look up the external flash memory region" be fixed, but there have other issue, I am investigating

pyocd.core.exceptions.TransferError: No ACK received
flit commented 4 years ago

The "No ACK received" error indicates that the device is not responding to SWD at all. Usually this means it is powered down or in a deep sleep state. On some devices, SWD can be disabled while the boot ROM is running, or for a short period during reset.

(If the error happens when trying to connect, you can add -Oconnect_mode=under-reset to the command line to try connecting under reset. But in your the problem seems to happen while the flash algo is running.)

Also please try the HEAD of the master branch. #845 fixed some RT1052 issues.

lgl88911 commented 4 years ago

@flit Thanks for your suggestion. HEAD of the master branch haven't this issue, 0.25.1.dev46 test pass.

flit commented 4 years ago

cool! thanks a lot for letting me know.
