…d rng driver Update with the latest nordic hal which includes an updated CRACEN driver which supports the 54LM20 and newer devices Signed-off-by: Alberto Escolar Piedras <alberto.escolar.piedras@nordicsemi.no> (cherry picked from commit ce0d65a35c0e0fdd89c7b697708615e09c04c70c)
Update hal_nordic with nrf_uarte change. Add functions for setting PTR and MAXCNT separately. Upstream PR #: 92767 Signed-off-by: Krzysztof Chruściński <krzysztof.chruscinski@nordicsemi.no>
Timer property indicates which TIMER instance should be used for byte counting. If timer property is present then given instance is using TIMER to count received bytes. Upstream PR #: 92767 Signed-off-by: Krzysztof Chruściński <krzysztof.chruscinski@nordicsemi.no>
Rearrange code to prepare for upcoming extension that adds special receive mode. Upstream PR #: 92767 Signed-off-by: Krzysztof Chruściński <krzysztof.chruscinski@nordicsemi.no>
Add reporting about the test progress. Test lasts few seconds and progress report helps to see if test stuck or how it is progressing. Upstream PR #: 92767 Signed-off-by: Krzysztof Chruściński <krzysztof.chruscinski@nordicsemi.no>
Extend test with a mode where HWFC is off and receiver is providing buffers on time. In that case receiver should be able to continuously receive data without losing any byte (even without HWFC). Additionally, TX data is chopped to verify that receiver does not loose bytes when new TX data collides with detected RX timeout. Upstream PR #: 92767 Signed-off-by: Krzysztof Chruściński <krzysztof.chruscinski@nordicsemi.no>
… for nrf54l Add timer property to the uart device under test. Add zephyr,pm-device-runtime-auto to the uart device under test. Upstream PR #: 92767 Signed-off-by: Krzysztof Chruściński <krzysztof.chruscinski@nordicsemi.no>
…nfiguration Add workaround timer to instances that are used for reception in the test. Upstream PR #: 92767 Signed-off-by: Krzysztof Chruściński <krzysztof.chruscinski@nordicsemi.no>
…andling Stress test is executed on CPUs with slow clock (16MHz). Handling of test data in UART_RX_RDY event is optimized to reduce time spent in the interrupt context. Since payload is always a decrementing sequence, fixed array is used to compare memory which allows to use standard memcmp instead of byte by byte comparison. Upstream PR #: 92767 Signed-off-by: Krzysztof Chruściński <krzysztof.chruscinski@nordicsemi.no>
…counting Add mode to be used on UARTE with frame timeout which is using a bounce buffers and TIMER to count bytes. This mode shall be used to reliably receive data without HWFC as frame timeout approach is not 100% reliable because it can loose or corrupt a byte when new byte arrives after frame timeout is detected but before it is fully handled. This mode is similar to the one enabled with CONFIG_UART_x_NRF_HW_ASYNC but additional bounce buffers are used and UARTE is receiving data to internal buffers and copies data to the user buffer. Legacy apporach cannot be used because in new SoC DMA attempts to copy data in words so when byte is received it stays in the DMA internal buffer until 4 bytes are received or end of transfer happens then internal DMA buffer is flushed.
