SE05x: Applet update fail with "not enough NV memory"

[adinathmhatre]

Hi,

While updating applet for OEF A564, from applet version 6.0 to 7.2, got below error

App :INFO :PlugAndTrust_v04.02.00_20220524

We tried "se05x_Delete_and_test_provision", but still there is no enough NV memory.

What could be the reason for not enough NV memory?

Hi @adinathmhatre ,

What is the result out of "se05x_Delete_and_test_provision"? I am suspecting if there is still something left in the SE.

Normally if you run se05x_Minimal demo, you may have the free mem size such as 

Have a great day,

Hi @adinathmhatre ,

Thanks for the info! No issue out of "se05x_Delete_and_test_provision", and the requested update size for SEMS Lite is correct in the update file. The difference out of the reported free memory in the minimal example and what SEMS Lite requires comes from the requirement that SEMS Lite need continuous free memory. This amount of continuous free memory is reported by the SEMS Lite CLI:

C:\nxp\se_mw\release\SE05x-MW-v04.03.00\simw-top_build\se_x86\bin\Debug>sems_lite_cli_app.exe --getFreePHeap

App   :INFO :Using PortName='COM15' (ENV: EX_SSS_BOOT_SSS_PORT=COM15)

Opening COM Port '\\.\COM15'

      01 00 00 00    00 64 13 88    0A 00 65 53    45 30 35 31

App   :INFO :availablePersistentMemory 34720

App   :INFO :availableIDX 32

App   :INFO :Free PHeap Central Gap 34208

App   :INFO :Free freeTransient 3808

SSS Status: SUCCESS

In case of situations where the Central gap is much smaller as the available persistent memory a memory compaction needs to be triggered. This can be done e.g. with deleting an object or running the example se05x_InvokeGarbageCollection.

Please kindly refer to "simw-top/doc/demos/se05x/se05x_InvokeGarbageCollection/readme.html" for more details.

Hope that helps,

Have a great day,
Kan

Hi @Kan_Li ,

Did you see any failure in "se05x_Delete_and_test_provision"? or you need any more information to check this?

Is there any possibility that chip itself has less NV memory?
