Re: [DEV] RP2040 support

Not sure how much you read the Raspberry Pi forums, so thought I'd just highlight that the hardware divider status needs saving in an interrupt (or the divider use gets placed in a critical section), in case that hadn't come to your attention. https://www.raspberrypi.org/forums/viewtopic.php?f=145&a...

Re: can reseved problem Topic is solved

It could be significant that the CAN hardware has three receive buffers.
Maybe you are not emptying the receive buffer fast enough?



(And how is this a "small change request"?)

Re: HAL I2C pin assignment

The assignment method looks OK.

Check that the I2C isn't also assigned to a second set of pins - behaviour is unpredictable then.

Re: [NOTES] Multi Core support

RTOS and HAL both compile in the demo, HAL is just a stub so far. I need to verify if it is possible to wrap the Pico SDK code in the HAL. Giovanni Good going. Will have a try when I find some time. Are you using one Pico as a debugger? One trivial thing I noted in the scatter file; the Pico has 2M...

Re: I2C on OLIMEX-STM32-LCD (STM32F103ZE)

The "standard" I2C driver (NOT the "fallback" driver) works for me on PB8/9, using the same configuration data as you. (I am using a driver which also supports I2C slave, but the master part is basically the same). You definitely need to configure the ports as open drain outputs ...

ChibiStudio - show hexadecimal values, screen copy/paste

Could ChibiStudio exceptions show values in hexadecimal rather than decimal? (Would save having to convert). For example in DebugProxy.java (full path D:\ChibiStudio\svn_osdn\branches\chibistudio_trunk\tools\chibios-rt6_debug_support\src\org\chibios\tools\eclipse\debug\utils\DebugProxy.java in case ...

Re: [NOTES] Multi Core support

Thanks, boards are readily available now so there is no need. Better than over here - 6-8 weeks from my normal suppliers! And here's where they started. It would be great if they merged RP2040 support in main OpenOCD anyway, are they stuck with that? I'm sure the Pi people will do whatever's needed...

Re: ChibiStudio 2020

Is the pointer xxxxxxx a valid address when this happens? perhaps the plugin is trying to fetch data from an invalid address. Giovanni Yes, valid address. It's the address of the function name which was active when my breakpoint was hit - usually an ISR. [Side note: The code listing doesn't list al...

Re: [NOTES] Multi Core support

Hi, About RPI Micro, I have not forgot, I got picoprobe and openocd working but I broke my other board, something went wrong when I soldered the headers or with wiring (my sight is no more that good...). I am waiting for more boards but the thing is progressing, I still find it very interesting. Gi...

Re: ChibiStudio 2020

When using a demo, I can refresh on the TraceBuffer fine, and still works fine if I turn off tickless mode. When I use my code, the refresh takes a long time, then pops up an error message. The popup title bar is: ChibiOS/RT Views The error message is: Error:error reading memory at 134401324 That a...
