RE: RTEMS booting problem for PICO-PI-IMX7 board.

Dear Huber, Please disregard my question about BSP_ARM_A9MPCORE_GT_BASE, BSP_ARM_A9MPCORE_SCU_BASE. I checked this again. Because i.MX7 port use arm-generic-timer-clock-confg.c instead of arm-a9mpcore-clock-config.c, these ZERO value will not effect any problem for i.MX7. Best Regards, JunBe

RE: RTEMS booting problem for PICO-PI-IMX7 board.

Dear Huber, I think so. DTB is modified by U-Boot. I don't know the reason right now. I am checking u-boot source. But, Because clock-frequency variable of timer is disappeared in lastest Linux kernel, you need to review arm_generic_timer_get_config() in bspstart.c I checked "dtc command on Li

RE: RTEMS booting problem for PICO-PI-IMX7 board.

Dear Huber, At this time, I am using lastest u-boot 2018.03 version for using ums command. F.Y.I : https://community.nxp.com/docs/DOC-335475 ums command is very useful for me because RTEMS image and DTB file can be replaced easily. There is different feature by "fdt print" command. < MBa7x.dts

RE: RTEMS booting problem for PICO-PI-IMX7 board.

Dear Huber, I checked DTS file which you sent me shortly. There are different points; 1) chosen : MBa7x is configured for serial5(uart6). - I will add this in pico dts again as serial4(uart5) - This feature should be added not for modifying console-config.c. 2) timer : it is real problem. T

Hi It would be good to know if rtems_task_self() is expected to return the 'TIME' a.k.a rtems_timer_initiate_server() task id, when a timer created with rtems_timer_server_fire_after() fires. If it is then i will have to make up some work around, as quite a bit of code thats coming over from Thre

Attached is a DTS file reconstructed from the DTB presented by U-Boot. Please note that U-Boot modifies the DTB. It is the default DTB of this board: https://www.tq-group.com/en/products/product-details/prod/embedded-modul-tqma7x/extb/Main/productdetail/ -- Sebastian Huber, embedded brains Gmb

Re: RTEMS Shell attached to Socket

Hello Phil, you can use telnet to attach a shell to a socket. Here is an example: https://git.rtems.org/rtems-libbsd/tree/testsuite/telnetd01/test_main.c Should work also with the legacy network stack. -- Sebastian Huber, embedded brains GmbH Address : Dornierstr. 4, D-82178 Puchheim, Germany

RTEMS Shell attached to Socket

Dear all, I would like to use the RTEMS shell for a project but I need the shell to be attached to a socket and not just to a serial port. The documentation I found here Shell-Documentation says that this is possible but

Re: Timers in a task context

Hi, I think I've managed to narrow it down,. rtems_task_self() is documented as "If called from an interrupt service routine, this directive will return the Id of the interrupted task.",.. however if you run a timer server and your timer is initiated using rtems_timer_server_fire_after(), then rte

I believe that any Linux distribution which supports the platform such as raspbian should have the file? This is the freebsd approach now as far as I know.  Russ Sent from my BlackBerry 10 smartphone on the Virgin Mobile network.   Original Message   From: JunBeom Kim (EmbedCoreTech) Sent: Mond
