Re: HCFiler for Cortex M7

It's not clear to me how the files written by HCFiler on a Nucleo board are then read back from a Windows PC.
Should I move the SD card from the Nucleo to the PC to use the PC tools ?
Kind regards,
Stefano

Re: Context switch

I will investigate the ASSERT/ SVCTrap road. Thanks for the suggestion. I need to stay with a standard core like Cortex-M and a RTOS is not applicable in my target scenario for both memory constraints and context switch speed requirements. Also I would like to use Oberon. What I need is a solution f...

Context switch

I'm wondering if it's feasible to implement with pure Oberon code (of course Astrobe-specific) a simple cooperative multitasking for the STM32 M7 platform based on following assumptions: 1) each task is an Oberon procedure but with its own stack 2) each task explicitly gives control to other tasks (...

Re: Dump variables to PC

I have now found the solution. The CLI command must connect in "hotplug" mode:

st-link_cli -c HOTPLUG -r8 2007F5C8 12

Thanks for previous feedback.

Re: Dump variables to PC

The array is defined at module-level. Tomorrow I will check with the GUI utility instead of the CLI.

Dump variables to PC

I'm trying to fill an Oberon-07 array variable inside a program and, after program termination, dumping back the array from the PC. The array is defined as: VAR shared: ARRAY 32 OF BYTE; and filled in the init body as: FOR i := 0 TO 15 DO shared := i END; where I also print the physical addresses as...

Re: Upload and Run

Perfect!
I'm able to load programs with a plain copy to the USB drive and run then using st-link_cli -rst
I mostly use the Astrobe IDE to do this, but I needed a way to handle some batch scenarios.

Upload and Run

I would like to know, possibly, which are the commands /mechanisms internally invoked by Astrobe IDE for the Nucleo boards in order to carry out the following two actions: 1) transfer a binary image from PC to target flash memory 2) run the program previously stored in flash For custom purposes, com...
