nrf54l15dk: Failing to build with CONFIG_ENTROPY_GENERATOR #81001

Open rettichschnidi opened 2 weeks ago

rettichschnidi commented 2 weeks ago

Describe the bug

Building for nrf54l15dk fails when enabling Bluetooth and entropy drivers at the same time.

To Reproduce

  1. west build --pristine --board nrf54l15dk/nrf54l15/cpuapp zephyr/samples/hello_world/ -- -DCONFIG_BT=y -DCONFIG_ENTROPY_GENERATOR=y

Expected behavior

Build should work. As it does e.g. for the nrf52840dk: west build --pristine --board nrf52840dk/nrf52840 zephyr/samples/hello_world/ -- -DCONFIG_BT=y -DCONFIG_ENTROPY_GENERATOR=y

Impact

Need to chose between BT and ENTROPY_GENERATOR. Which in turn means that I can not enable e.g. BT and NETWORK at the same time.

Logs and console output

$ west build --pristine --board nrf54l15dk/nrf54l15/cpuapp zephyr/samples/hello_world/ -- -DCONFIG_BT=y -DCONFIG_ENTROPY_GENERATOR=y

Additional context

cvinayak commented 2 weeks ago

There is no supported entropy driver for nRF54L15 yet in the upstream Zephyr Project. When there is one, it will need to support its APIs being invoked from thread and ISR execution contexts, and change the code in link layer to use a DTS choosen entropy device.

nordic-piks commented 2 weeks ago

Triaged internally

rettichschnidi commented 2 weeks ago

Just realized: NETWORKING selects ENTROPY_GENERATOR. Therefore, a nRF54 based application can not support both, BT an IP communication. This limitation affects the product I am working on directly, pretty much rules out the usage of the nRF54L15. Prototypes used a nRF52840, which was no issue at all.

This fails:

west build --pristine --board nrf54l15dk/nrf54l15/cpuapp zephyr/samples/hello_world/ -- -DCONFIG_BT=y -DCONFIG_NETWORKING=y
rettichschnidi commented 2 weeks ago

Adding CONFIG_ENTROPY_BT_HCI=n allows the build to succeed. I do no know the consequences of this however.

This builds (-DCONFIG_ENTROPY_GENERATOR=y):

west build --pristine --board nrf54l15dk/nrf54l15/cpuapp zephyr/samples/hello_world/ -- -DCONFIG_BT=y -DCONFIG_ENTROPY_GENERATOR=y -DCONFIG_ENTROPY_BT_HCI=n

But this (-DCONFIG_NETWORKING=y) still does not:

west build --pristine --board nrf54l15dk/nrf54l15/cpuapp zephyr/samples/hello_world/ -- -DCONFIG_BT=y -DCONFIG_NETWORKING=y -DCONFIG_ENTROPY_BT_HCI=n

For testing purposes with networking enabled, you could set CONFIG_TEST_RANDOM_GENERATOR=y to get things compiled. This is not a permanent solution as the generated random numbers are not truly random.

@jukkar hmm... i was not aware of this, can I use this in nRF54L Controller on target? (yes, of course it is test generator) it does provide the Zephyr Entropy APIs and dts node to be chosen, right?

jukkar commented 2 weeks ago

I have used this Kconfig option to test networking things when random number generator is not available. Not sure if it would work for you in your use case.
