I have encountered three problems using CircleOS 3.5 on Primer1.
The first problem is that CircleOS shows both in system test and in the battery picture 0.00 V.
The second problem is that CircleOS eats 32 kb, and this is one quarter of the flash memory. That means that the command "Circle_Mgr L S" shows 72 kb on empty device (i.e. without any program installed) instead of 104 kb. Same goes for the "About" dialog. Downgrading device to CircleOS 2.0 still shows 72 kb with Circle_Mgr, but shows 104 kb in the "About" dialog.
The third problem is the button sensitivity. On CircleOS 3.5 it is much lower than on CircleOS 2.0 or 1.7 . Every second button press gets lost.
I de- and re-installed both RIDE7 and GCC toolchain. The versions are:
Ride7 IDE 7.16.0000 RKit-ARM for Ride7 1.16.0930
Is it possible to solve these problems, apart from downgrading to CircleOS 1.x?
We modified the memory map for CircleOS 3.5. Now, the program is split (as for Primer2) in two parts: the bottom memory from 0x08000000 to 0x08005F00 (as for the former versions of CircleOS) and the top memory (the very last 8KB). We made this change (using a segment at the top) because it was always tricky to reduce the code size and to keep it in the first 24KB. There is now enough space for future evolutions...
I forgot to say that the split is done by considering a 'non_debuggable' section in the LD file. This section contains the code that is used only at initialization and in the main menu of CircleOS. The rest of the code (possibly called by the applications trhu the API) is still in the debuggable area. It could be also a way to extend the 8KB debuggable for the application (probably 12KB could be ok).
and I answered to Wincent (thanks Wincent) that the fix will be in the next release (3.7).
By the way, could you elaborate on freeing some flash space in CircleOS 3.6 for applications?
That has been done for Primer1, but it's not possible for Primer2 (the debuggable area is full... and the FS files are already not-debuggable).
Hello Francis,
first, you are right, I should have to quote your answer too
second, I still have the problem with space. The CircleOS 3.6 "About" menu shows 88 kb of flash space, but Circle_Mgr L S still shows 72 kb. What do you think about that?
Sincerely,
wincent
P.S.: And it is for a first time a pleasure to see battery level sinking
We will check and answer tomorow. Extending the debuggable space has been quite easy, but using it is probably more complex (FAT.ELF need to be modified and the .LD files as well). Because I don't think that we released a new 'CD-ROM' image, we have to write a short 'application note' to explain how to use the extended space provided by the new CircleOS.
Francis PS: and we have also to check the amount of memory displaid in 'About'..
I apologize: the current CircleOS (3.6) has not been changed to extend the debuggable area (that is much larger). To extend the debuggable area: 1. Open the circle.rprj project, and in circle.h, modify the FAT address (from 0x8006000 to 0x8004000): #ifdef PRIMER1 # define VDD_VOLTAGE_MV 3300 // Voltage (mV) of the STM32 # define FA_TABLE 0x8004000 // >>>>>>> INSTEAD OF 0x8006000 <<<<<< #endif Rebuild the project, and you circleOS is now ok. 2. Copy the resulting circle.elf file into "Program Files\Raisonance\Ride\Lib\ARM\CircleOS" 3. Modify the LD (circle_app.ld) file of your project (to be debugged) to relocate the code at 0x08004000 instead of 0x08006000. FLASH (rx) : ORIGIN = 0x8004000, LENGTH = 16K instead of FLASH (rx) : ORIGIN = 0x8006000, LENGTH = 8K 4. Last issue: you have to regenerate a FAT.elf file for debugging. This file contains only a word value at the address '(FAT_TABLE - 4)' initialized with (FAT_TABLE). Thus, it used to be 0x08006000 at 0x08005FFC, and we want now 0x08004000 at 0x08003FFC. Here is the original file we used for this purpose:

I apologize: the current CircleOS (3.6) has not been changed to extend the debuggable area (that is much larger).

Hello Francis,
now after I applied the changes you described (by the way, what about the Fat.ld? Did you forget to change from 5FFC to 3FFC or is it intended? I changed it.) I got another 8 kb (+ 72 kb = 80 kb on the empty CircleOS together). Now after I installed the apps "Circle_Mgr L S" tells me I still have 41 kb, but the "About" menu says I have 49 kb.
Yes, I forgot to modify the LD file. I included it here because it was not available neither on the original CD nor on this web site. At the moment, the amount of memory reported by both Circle_mgr and 'About' is not dynamic because we don't store the information about the size of the FLASH used in the upper memory.. We will modify CircleOS in such a way that we will find this information. Don't pay too much attention to this information for the moment. Are you able to debug your application from 0x8004000 ?
Are you able to debug your application from 0x8004000 ?
For debugging I use DRAW_DisplayString() . As I get to use the (circle) primer in my everyday life, it bugs me to backup the programs every time I sit down to write an application and to restore them before every installation.
Hence, I am afraid, you will have to wait for results from another developer which uses debugger extensively.
