Application raised Data Abort in first instruction

Hello all I'm running rtems on tms570lc4357 , flash loaded with HalCoGen generated loader, rtems application is loaded by gdb into SDRAM. the RTEMS bsp / boot_card is started and broke in first line of hello.c:Init but when booted in simple hello world task, it raised exception to 0x18, seems dat

Re: How can I use --with-rtems-bspopts properly?

Well Just only use `TMS570_USE_HWINIT_STARTUP=1 ARM_TMS570LC4357=1 BSP_MINIMUM_TASK_STACK_SIZE=2048` after configure will make the configuration. I thought --with-rtems-bspopts should do it. On Fri, Sep 16, 2022 at 5:45 PM Y. HB wrote: > Hello, > > I am working on tms570 bsp >

How can I use --with-rtems-bspopts properly?

Hello, I am working on tms570 bsp I want to change some bspopts , but I cannot get the default value overridden via --with-rtems-bspopts, what correct way should I do? I used following command to configure RTEMS bsp ../../rtems-master/configure OTHER-OPTIONS --with-rtems-bspopts="TMS570_USE_HW

Is most drivers interfaces should be driver or application specific?

Hello all. I'm writing drivers ( like ADC ) for tms570 on RTEMS. To my understanding for now, there are two ways to implement non common interface drivers. 1. write a specific driver.h/.c pair to be called like PWM driver inside bsps/arm/beagle/ 2. use I/O Manager interfaces. The latter IO Manage

What is the preferable way to add new BSP (for stm32 family)

I have seen in rtems 6.0, there are two stm32 families: stm32f4 and stm32h7 The former one uses custom code to set up BSP, while the latter one uses the ST provided HAL lib to set up BSP. Now I need to add a BSP for stm32f3, which is very different (reg layout) from stm32f4. To add stm32f3 BSP a

Hello. Sorry for the last message, it was sent by accident. I have known that the STM32F4_GPIO_CONFIG_TERMINAL is used inside start-config-io.c, and used as a termination of set_config_array. On Fri, Sep 9, 2022 at 3:40 PM Y. HB wrote: > STM32F4_GPIO_CONFIG_TERMINAL is defined in rtems(

What is meaning / usage of STM32F4_GPIO_CONFIG_TERMINAL

STM32F4_GPIO_CONFIG_TERMINAL is defined in rtems(5.1) bsps/arm/stm32f4/include/bsp/io.h What is it ? And How the value is filled from the Datasheet or Reference Manual of STM32? ___ users mailing list users@rtems.org http://lists.rtems.org/mailman/listin

Is rtems interrupt latency good enough for BLDC ESC? (on arm cortex-M or cortex-R)

Just Curious, As for the title. I found an old article: https://docs.rtems.org/releases/rtemsdocs-4.6.0pre5/share/rtems/html/supplements/m68k/m68k00062.html, it said rtems's interrupt latency on MC68020 is The maximum period with interrupts disabled + 9 microseconds on 20Mhz. I see zephyr provid

Failed to start RTEMS on tms570lc4357 loaded from SDRAM

Hello, I'm still working on bringing RTEMS on tms570lc43x. Although I can start RTEMS from tms570 flash, but to minimize flash erase cycles, I want to load RTEMS from SDRAM like said in RTEMS wiki. I started a flashed program generated by HalCoGen, and loaded the program to SDRAM by gdb. However

How can I run RTEMS kernel from SDRAM on TMDX570LC43 HDK?

Hello, About two weeks ago, I worked in running RTEMS (5.1) on TMS570LC43 Launchxl, and it booted and print via uart. But when I tried to build CFS on RTEMS, it failed due to not enough memory, so I bought a TMDX570LC43 HDK with 8MB sdram on it. As indicated in https://devel.rtems.org/wiki/TBR/B

I added -lm in LDFLAGS in my custom bsps/arm/tms570/config/xxx.cfg the flag is added to compiling arguments, but it still reported undefined reference to 'floor', but I see there is floor symbols in the arm-rtems5/lib/libm.a Why is it? Thanks On Fri, Jul 22, 2022 at 1:43 PM Y.
