Hi,   from the documentation: • PINT0 can sense pin activity on PORTA and PORTB • PINT1 can sense pin activity on PORTB and PORTC • PINT2 can sense pin activity on PORTC and PORTA   However, I don't fully understand the mapping of ports to the PINT_ASSIGN register. Can you please elaborate a bit on it? I'd like to have a pin interrupt on… (Show more)

Current PPI Setup: RX Single external frame sync Configure several DMA buffers to receive 2048 byte block maximum size block PPI Count register is 2048 Is it possible to configure PPI RX to receive different size blocks with reinitializing DMA and PPI?   The issue is the TX device transmitting to the BF can interval variable length data… (Show more)

Question:   Usually there is a linker switch to get total code and data size. I am unable to find it in the case of Blackfin linker. I could calculate this from map file, in example by a python script. Is this kind of script done already done?   ========================   Answer:   MAP file is the easiest way to get the size information.  …

Hi All,   I'm working on debugging a BF537 project. I'm finding that my program stops functioning as expected with the Call Stack stuck in  <___wab7 + 0xceaeef3a>.   Can anyone shed any light on what (where) is `___wab7` is and what this event means?   Thanks in advance -Matt

Hi All,   I have a custom board with a BF537 si 0.3. Upon boot up, a simple assembly boot loader is loaded off of sflash. The boot loader configures PPL, EBIU, etc. Then it loads the main program from sflash. Clock in is from a 25MHz crystal. MSEL=19, DF=0, BYPASS=0, SSEL=5, CSEL=0.   The relevant section of our boot loader is: CLI R2; //… (Show more)

Hi All,   Is there a way to determine if an interrupt is currently nested? That is to say, while servicing the interrupt can I determine if there is another interrupt (of the same type) pending?   I'm using a BF537 with VDK   Thanks in advance. -Matt

Hi ! Is there a possibility to do a reset by software which is the same as a reset per hardware ?   I work with following statements but i'm not shure if it realy resets Core&Peripheral - take from page 1001 of hardwareReference Manual   Watchdog reset is not possible because this is handled specialy on startup   *pSWRST=SYSTEM_RESET;… (Show more)

Hi,   the __sec_int_dispatcher is installed as the handler for IVG11 and also referred to as SEC interrupt dispatcher. I am currently facing issues when an interrupt is interrupted by another interrupt (i.e. nested interrupts). I'd like to disable interrupts during the handling of the SEC.   Is this possible, a good idea?   What would be… (Show more)

Hi all   Please understand that UART slave timing diagram of H / W reference manual does not understand well.   Fig 36-8 Host Relying on RTS I know that using uart0 to download, but can uart1 also download the program? Is RTS controlled by BF706 when sending data from BF706?   Fig 36-9 UART Autobaud Detection Waveform there art two… (Show more)
