Re: STM32F3 ports

Yes! It seems to be different from STM32F091 also...
Probably I'll have to find a book for getting around this kind of issues ...
Nothing I used to know seems to look like c language used in here!
Is there any porting guide for uPy? Google didn't help with this either.

Thank you!

Re: STM32F3 ports

Hi,
I made one step forward, but still in error!
Can't figure out what should be in here!
I've tried to compare with files on st.com ... but it doesn't seem to work!
Any ideas?

Thanks,
Romeo

Re: STM32F3 ports

Which cache are you referring to? It looks like the flash memory on the STM32F303xC is arranged as 128 pages of 2Kbytes each. On the F4 it has much larger flash blocks, so the 64K CCM memory winds up getting used for the filesystem. On the F303 it looks like there is 40K of SRAM and 8K of CCM SRAM....

Hi!
Just finished the dac and adc!
The only thing I cannot figure out where to set the cache and how big should be ...

The rest is updated on github.

Any suggestion for the cache?

Thanks,

Re: STM32F3 ports

Ok. Applied patch. Returned to old _af csv (with CAN, not CAN1).
Updated repository.

Re: STM32F3 ports

Hi, Thank you. I came around with CAN by naming it CAN1 (since is the only one). For LED I doubled the LED3 and named it LED2. On the board LED1 and 2 are attached to ST-LINK programmer. Now seems to be and error of dma, flash, ... and I stoped the script to get the screenshot. I updated the reposit...
