Hello,
ADSP-SC587 interfaced with ADSP-BF561 through SPORT in our custom board, issue is when we set clock frequency 1 MHz communication between the processor is fine. But when we increase the clock frequency, clock is getting deteriorated. Our requirement…
ADSP-BF536 - RTC Power Consumption - solution for UL certified application...
In order to get a UL certification, we designed in a 1K series resistor to the RTCVDD pin. This value resulted from the requirement, that according to UL, a battery must not…
The difference is in the recommended VDDINT voltage level. As long as you follow voltage specifications and provide adequate current according to the ADSP-BF534/ADSP-BF536/ADSP-BF537: Blackfin Embedded Processor Data Sheet (Rev I, 07/2010) you…
Hi Ali,
The most likely reason that you're not getting CLKOUT and not able to connect over JTAG is that you are not meeting the power-up reset requirements of the BF537. RESET must be held low for at at 3500 CLKIN cycles after all voltage supplies are…
Hi Tommy,
The adi_ports file is for the Port Control Manager. As detailed in the Device Drivers and System Services Libraries Manual, the port control manager service is available for Blackfin processors that support port control. Port Control is standard…
The compiler did work, it is just the final link that has the problem. I will have to see about sending you a copy of my project/makefile as I don't want to post it here (it is pretty big so I would like to try to simplify it before I send it to you privately…

When uClinux is built for the BF536 processor it panics. I've tried this on my own BF536 based board and on the BF537-EZKIT. The BF536 build should work on the…
Hi Sam,
Power numbers for ADSP-BF54x processors are provided in the device datasheet (Tables 16 & 17 Static Currents, Table 18 Activity Scaling Factors and Table 19 Dynamic Currents).
For help estimating power consumption, please refer to…
