Re: Copying a Procedure to RAM
I can't think of a general way to copy the executable code of a procedure to RAM that would be both useful and reliable in the current implementation of Astrobe for Cortex-M. Note that Astrobe for RISC5 supports the dynamic loading of modules (but not isolated procedures) into RAM. What is the actua...

Re: SET Parameter Problem
Thank you for your report. The problem will be fixed in v9.2. In the meantime a workaround is to assign the set to a local variable before passing it as a parameter. See the attached test program which should display the string "OK". Replacing the local variable assignment s := {k}; Check(s, k) with...

Re: Buffer Address for DMA
But non-VAR parameters? I would have expected to get a stack address, but for RECORDs and ARRAYs we get the actual address, VAR or not VAR. This is a subtle consequence of Section 10.1 of the Oberon-07 Language Report: A value parameter corresponds to an actual parameter that is an expression, and ...

Re: Buffer Address for DMA
Try:
Code: Select all
DMA.SetMemAddr(chan, SYSTEM.ADR(s)); (* set memory address for DMA channel *)

Planned deprecation of SYSTEM.LNK, SP and PC variables
We have discovered some reliability issues while running regression tests on v9.0.4 Astrobe for Cortex-M3, M4 and M7. These are related to the SYSTEM.LNK problem . A number of the instructions generated e.g. TEQ, TST, CMP etc. are documented as, for example: if n == 15 || m IN {13,15} then UNPREDICT...

Re: Interrupt Handlers
Good question! Actually Cortex-M0 is OK but Cortex-M3 could be optimised. Try adding some code to your Cortex-M0 interrupt handlers. You should see some or all of registers r4 - r7 saved if they are allocated by the compiler in the handler. Additionally, all registers r4-r7 are saved if another proc...

Re: Using Astrobe RISC5 with RISC5 emulators
You could use Astrobe's editor and code navigation features to work on source code modules which you would then transfer to Peter's emulator using its file transfer features. You would then compile these modules on the emulator. However, you would need to avoid using any of the Astrobe-specific exte...
