Hi, I'm having problems with Zephyr's file system. I am building on the board qemu_cortex_m3 on Linux. I'm getting the following error when I'm building: Any help would be much appreciated. Thank you.

Hi, You can just change it whatever you like it. In our case btproxy creates /tmp/bt-server-bredr and qemu connects to it and present to guest OS as a serial device. Best regards Andrei Emeltchenko

Hi Yie, That seems really weird. Could you attach the output of ram_report and rom_report in a pastebin/gist/attachment? And if that's not a problem, please provide your .config file. You can find it

Hi Hui, Newlib is included in zephyr. To enable newlib, just add CONFIG_NEWLI_LIBC=y to prj.conf file. The conf file can be found in the same directory that your makefile is. Then your zephyr

Hi, Is there a way to include C libraries that are not in Zephyr e.g. <unistd.h>? Cheers.

Hi Andrei, Thanks for your reply. Are there any other QEMU_EXTRA_FLAGS that allows applications to communicate with one another without using bluetooth? Like named pipes in C? Cheers.

Hi Tamra, Flash sample/synchronization/ application you will be able to see the prints. Flashing via dfu-util for tinytile works fine. After flashing "hello world" sample application ,a reset is

Hi Tamra, I don’t have a tinytile at hand, but you might want to try the following command: ZEPHYR_FLASH_OVER_DFU=y make BOARD=tinytile flash You will find more information about

Hi, We use QEMU_EXTRA_FLAGS for providing this parameter for QEMU, for example in bluetooth we may run btproxy on Linux host and QEMU_EXTRA_FLAGS like following: QEMU_EXTRA_FLAGS = -serial

Hi, Is there an inter-process communication functionality on Zephyr running on Linux for Qemu? I have an application on Zephyr that gets data from an external source. However, since I do not have the

Hello all, I am trying to flash my tinytile. When I use the commands make BOARD=tinytile flash or make flash or the dfu-util command, I get the errors below. Tinytile does not have a jtag connection

I see. That makes a lot of sense. Thank you Maciek! I have another question, if you dont mind. I have an app that's taking about ~5MB of RAM and ~5.6MB of ROM judging from the 'ram_report' and

qemu-system-arm is just a VM that can emulate, among others, Cortex-M MCUs. `qemu_cortext_m3` board is in fact emulated by qemu. Memory usage of a running Qemu process does not directly (or

Hi Thiago, Thank you so much for the reply. I am running Zephyr on Linux and building the hello_world app on ARM using qemu_cortex_m3. I've got the numbers from the following: The 8MB of memory is

Hi Yie, That definitely isn't right. In which environment are you running Zephyr, and how are you measuring this? Try 'make rom_report' and 'make ram_report' to get a nice report of how much each

Hello David, I appreciate the detailed response, with many points coinciding with what I wrote previously. And my hypothesis that many of these points would apply not just to "hobbyist" usage, but

Hi, I read that Zephyr allows small footprint of a few KBs. However, the sample hello world application already takes up 8MB of memory and has a size of 3.8MB. I am not sure if I am running this

Hi, I am currently running a HTTP client in QEMU_cortex_m3 and I was trying to set the timeout for the http_client_send_req(..) function and it doesn't seem to work. It still does not return

Hi, As part of the migration to Github Issues, we moved the SDK Jira project and made the Jira project read-only. All new SDK issues should be reported to

I definitely think it makes sense to do this by default for our QEMU based targets, since they have lots of ram and we don't gather performance metrics for emulated targets. Andrew
