Error -134 running Crypto samples on Thingy91

[Sly Gryphon]

I'm having trouble running the Crypto samples on Thingy91.

I did get samples/crypto/rng to work, which just generates random numbers.

But samples/crypto/hmac fails with: psa_generate_key failed! (Error: -134)

And samples/crypto/sha256 fails with: Could not setup the hash operation! Error -134

I am building with `-b thingy91_nrf9160_ns`. 

This is not listed under boards, but nrf9160dk_nrf9160_ns is, with some conf changes for CONFIG_BUILD_WITH_TFM=y and CONFIG_TFM_PROFILE_TYPE_NOT_SET=y.  I tried adding these settings to the thingy91 build, but it gets a compile/link error that FLASH is overflowed.

Does the Thingy91 support crypto, or does it not have enough memory, or could there be some other problem?

Some additional details.

* I came across this doing some extension work on the Azure IoT Hub sample (looking to get shared key working), so this was v2.3.99
* Confirmed the issue happened in the basic crypto samples (i.e. not my code)

I do currently have a work around, using a direct implementation of HMAC + SHA256 from https://github.com/h5p9sl/hmac_sha256 , as the code is not that much.  But it would be good to have the standard crypto working.

Hi,

I have built unmodified crypto samples hmac and sha256. Both samples have been built successfully for thingy91_nrf9160_ns build target using NCS v2.3.0.

Best regards,
