Hi, I have a problem with my application: I developed an update procedure that recive the new firmware, store it in sdram and then write it to flash memory. It worked fine until now: I noticed that when my .ldr file becomes larger than about 635KB the procedure work fine but very slow (20 minutes against 1 minute). I see that each falsh sector… (Show more)

I'm having trouble configuring the EPPI interface on a BF-548 processor.  I want to use the interface to sample 4 to 8 inputs at high speed using DMA for a sort of bit-banging input application where I periodically process the received data.  I'm using the General Purpose 0 Frame Sync (GP0) mode as frame sync isn't important in my application.  I… (Show more)

Hi Everyone   Iam using ADSP BF-548 processor in my project,i need to acquire data from ADC and i need to perform real point FFT to the sample acquired,my sampling rate is 8200SPS and FFT interval is 500msec,i need to perform 4096 point FFT,when i feed 1khz with 1Vpp i am getting magnitude as approx 0.43volt,but when i give 999hz or 1001hz with… (Show more)

# Hi! I am using BF527 custom Board. I have modified INETD echo server application for my application, I have used Server threads with three ports for handling three different clients with associated Receive and send threads to handle data. A have used another thread for embedded application with timer Interrupt. My problem is When I am testing… (Show more)

What is the best way to interface 2 ADAR7251 chips to a BF707 so as to allow the maximum sample rate of 1.8 MS/s?

I'm supporting obsolescene for an EOL flash chip (a Micron mt29f2g08abaeah4it ), and I've thus far found a drop-in replacement (Macronix MX30LF2G18AC-XKI ) that is identical in all aspects. These flash chips are used in a few devices that use the BlackFin BF54x family as the host processor.   Both chips are ONFI 1.0 compliant with their command… (Show more)

I need to generate several sine waves concurrently. Some are fixed freq., some are a single freq. which is selected by the control s/w and the freq. can change due to operator input, and 1 or 2 must be a scanning freq over a certain range. The sample rate is 48KHz. The processor is a Blackfin 548. I am not very familiar with the Blackfin but I… (Show more)

Hello, dear colleagues! Could You send a link to download SPI driver for ADSP-BF514F16 (note. - SPI driver for ADSP-BF158F16 is not applicable for ADSP-BF514F16).   Thanks!   Sincerely, Kirill

Hi!   When I try to build the project from the VOS_Outdoors_FileIO_BLIP2 project example I just get the following error:  make: *** No rule to make target `../../../../../../../../../../../../Analog Devices/CrossCore Embedded Studio 2.8.0/Blackfin/include/sys/platform.h', needed by `system/startup_ldf/app_cplbtab.doj'.  Stop.   What can I do to… (Show more)

I have a custom Blackfin 533 design which can be hibernated. During hibernation, only VDD RTC is available. Wake Up from hibernation is successfully provided by an interrupt from the RTC on its 1 Hz tick. After a wakeup, my specification requires me to test for the presence of a known analog signal. This is implemented by a short section of… (Show more)
