Fwupdate does not write NuttX correctly

In SPRESENSE SDK v2.3.0, we created two firmware with examples/fwupdate, examples/hello, and feature/usbmsc.
One has not touched the source ("Hello, World!") and the other has changed the display of examples/hello.

nsh>hello
Hello, sense!!

Packaged the original source nuttx.spk in conjunction with loader.espk.

$examples/fwupdate/package.sh sdk/nuttx.spk firmware/spresense/loader.espk
Pack: 118752sdk/nuttx.spk
Pack: 129968 firmware/spresense/loader.espk
====================
Created package.bin
====================
$ cp package.bin hello.bin

I wrote this to SD to see if it can be updated with fwupdate, but NuttX does not appear to be updated correctly.

Is there something wrong with using fwupdate?

I think the usage is correct, but it is strange that the nuttx.spk type is 1.
Pack:1188752sdk/nuttx.spk

If you run the same command in your Ubuntu environment, the nuttx.spk type is 0, and the firmware update is working properly.

$examples/fwupdate/package.sh sdk/nuttx.spk firmware/spresense/loader.espk
Pack:0148912sdk/nuttx.spk
Pack: 129968 firmware/spresense/loader.espk
====================
Created package.bin
====================

I think the wrong type is the reason why it doesn't work.

examples/fwupdate/package.sh is a simple script, so I checked the contents, but if the basename command retrieves the filename and the string nuttx, the type seems to be 0.I'm not sure if there is an environmental dependency problem or what is causing it, but the basename command may not be the intended behavior.

What do I see when I run the following command under the spresense directory?The expected result is nuttx.spk.

$cd spresense
$ basic sdk /nuttx.spk

Why don't you move the directory to spresense/sdk and run the following command?The expected result is also nuttx.spk.

$cdspresense/sdk
$ basename nuttx.spk

It's not a clear answer, but I think it's better to check the behavior of the script.
