Secure Provisioning Tool v3 fails to write image

[kanimozhi_t]

Hi,

I recently downloaded the latest MCUXpresso Secure Provisioning Tool version 3[b210414] for Ubuntu 20.04 and it fails while writing the secure image to the connected i.MX RT 1060 (GENERAL ERROR:unpack_from requires a buffer of at least 4 bytes for unpacking 4 bytes at offset 0 (actual buffer size is 2)blhost failed).

I've been using the version 2 without any problem for some time now. So my question is there a known bug in the latest version on Linux?

Error log is attached for your kind reference.

Hello kanimozhi_t,

Allow me to check if we have reports of this being a known issue. I will let you know as soon as I have more information.

Hello kanimozhi_t,,

The suggestion from the SPT team is to replace the spsdk blhost tool by legacy tool and check if the issue is still reproducible.

This can be done by editing the file MCUX_Provi_v3/bin/data/targets/MIMXRT1060/MIMXRT1060.json in a text editor and at the end of the file change:

        "blhost": {

            "type": "spsdk",

To:

        "blhost": {

            "type": "legacy",

then restart the SPT tool.

Even if this workaround help, would you please post your issue on the SPT Tool Support Community (link below) and include your application binary is possible? This would allow the SPT team to try to replicate this issue so that they can fix it natively (without having to use the legacy workaround).

I hope that this helps and thank you for pointing this out!

Regards,
Gustavo
