That's right! In RISC-V terms, Machine mode has access to all system resources and is the mandatory mode to implement. Supervisor mode has a different usage model, which I guess used for

Thanks. Actually I want to remove any supervisor mode access in the code. We don't want to have mmu. We want to run in user/machine mode. I got your point on usermode. Is there a way I can turn off

Hi Devs! Compiling a Zephyr project with target nrf52_pca10040 the sys_rand32_get() works well. But when the target is FRDM-KL25Z the compiler show this error: undefined reference to

Hi, User mode is currently only supported on x86, ARM, and ARC CPUs. The documentation uses "supervisor mode" to refer to non-user mode, i.e. all CPU instructions may be executed and all memory

Thanks Filip, I'm just starting to learn Zephyr and looked thru all the examples but never thought to look in test. Thanks again. __ Ormund

Where did you find this information? For RISC-V SoCs, the supervisor mode is only used when the base architecture has the 'S' extension. Since there is no Supervisor enabled SoCs supported by Zephyr

Hi Zephyr supports supervisor mode. I want to nullify it at software level. corresponding dts , we are using is "riscv32-qemu.dtsi" regards, sathya -- regards, Sathya

Hi Sathya, Which SoC are you trying with? AFAIK all supported SoC's only incorporate Machine mode access, not even User mode. Supervisor mode is meant for a full-fledged operating system. Thanks, Mani

Hello Ormund, For example of using SPI you can take a look at tests/drivers/spi/spi_loopback. Config for nRF52840 DK is at tests/drivers/spi/spi_loopback/boards/nrf52840_pca10056.conf, also please

Hi, Is there a way to run zephyr only in user/machine mode ? I am trying it for riscv32 architecture. We dont want to run in supervisor mode. Please let me know note: I am new to zephyr

Hi All, I was looking for some example code showing how to use SPI on an nRF52840-DK board, especially selecting the pins that will be used. Regards. __ Ormund

Hi Johan, I don't have a Bluetooth adapter on my machine and "hciconfig" does not show any device available. Thanks, Marco -- Sent from my Android device with K-9 Mail. Please excuse my brevity.

Hi This is seungwoo We will contact you regarding the development of BLE. I am trying to develop a device using nrf52810. I want to transfer files via BLE using the file transfer method used in

Hi Marco, Does your PC have a Bluetooth adapter? Does e.g. running "hciconfig" show hci0 for you? Johan

Hi, I'm experimenting with Zephyr and BLE I have few Nordic Semi boards and I've been able to successfully compile and run BLE examples for those. I also would like to use QEMU to test BLE examples

Hi, Sebastian, Thanks for the useful information. This is something I've been wondering about as well. If I understand you correctly, I think this would be an extremely welcome change. For example, I
