MCU-PLUS-SDK-AM243X: Exception in HWALLicense task in reboot test

Sven K

Part Number: MCU-PLUS-SDK-AM243X

Hello,

we had some problems in our reboot tests with SDK 8.4.0.17 and profinet Kunbus stack.

We got an exception from task HWALLicense. By analyzing the stack dump we found this .text labels from our map file:

====================================================

Mapping to .text Sections

0x501de890 | aligned_alloc

0x70164b27 | mbedtls_mpi_grow

0x70133cc1 | mbedtls_mpi_div_mpi

0x7016530d | mbedtls_mpi_mod_mpi

0x7012e533 | mbedtls_mpi_exp_mod

====================================================

After reboot we are waiting for connection establishment from Profinet Master Siemens CPU1518F-4 PN/DP. With a CPU1516F we had no problems.

Best regards, Sven

Based upon aligned_alloc appearing the stack dump, perhaps their was insufficient free memory on the heap.

What is the size of heap, and can you try increasing the heap size?

Hello Chester,

our heap size is 1MB. I will increase it and test if behavior is better.

Hi Sven,

Did increasing the heap size worked?

Hi Nilabh,

increasing the heap size seems to work

Best regards, Sven
