Class B Software for Cortex M3 CPU

We use the Cortex M3 CPUs (LPC1768 and LPC1517) in two projects for industrial door controls. The TÜV inspector complained that the internal watchdog was not sufficient for functional safety according to IEC61508.
What is your opinion about this ?

Are libraries available for testing the CPU that meet the requirements of IEC 61508?
On the follwing link a found no information regarding the Cortex M3 CPU´s

The IEC 60730 Class B Safety Library supported MCUs are all listed in this link as you know

https://www.nxp.com/products/product-information/iec-60730-safety-standard-for-household-appliances:APIEC60730

By checking, currently, it can't support other MCUs.

M3 product is not supported.
