1. For Version 2 0 and Later Your dspFlash should be automatically detected when it is plugged into the computer and added to the list of available dspFlashes upon its enumeration Setting Up Your Target Setting up a connection on the dspFlash is simple Step 1 Select the target processor To do this select the processor on the target board from the pull down box Step 2 Select your flash configuration at the current time both SPI and parallel flashes are supported If you are using a SPI flash the next step is to specify your chip select line by choosing it from the CS pull down box If you are using a parallel flash you have to specify either the memory select line that the flash is connected to or the base address The base address is user supplied for the ADSP 21262 and ADSP 21364 families and is used to signal the location of the flash to both the dspFlash programming module and to the target Step 3 Select the manufacturer of the target flash to be programmed then the model of the flash You no longer need to select the type of Idr file you are using because it is automatically detected Many file types can be written to flash If you are writing any sort of file that does not conform to ADI Idr file formats ASCII or Intel Hex will be written as a binary file If you are programming an audio file a video file or a binary loader file they will be written bit for bit as they are in the files Choosing and Uploading a file2.

3. dspFlashes Connecting to the target is as simple as plugging in the JTAG cable The target device can be either powered or unpowered when the cable is plugged in Once your target is powered the LED indicating the logic voltage level should light If this does not light you should refer to Analog Devices application note EE 68 which describes the proper JTAG connections specifically pulling pin 5 high via a pull up resistor If this resistor is not present the voltage level of the target is assumed to be 3 3V Configurations using lower logic level voltages without this pull up resistor are not supported by the dspFlash dspFlash User Manual Page 7 Target Hardware Requirements JTAG Requirements The JTAG connections to your target processor are assumed to comply with Analog Devices Application Note EE 68 The pin connections are required to be as follows Ground 1 2 EMU Key This pin should be removed 3 4 Ground Pulled to Vddio through a 4 7KQ resistor 5 6 TMS Ground 7 8 TER Ground 9 10 TRST Ground 11 12 TDI Ground 13 14 TDO Note If you have wired your JTAG for a Local Boundary Scan Controller then you may have different connections for these pins If you have wired for a local boundary scan controller then you will need an adapter on the target side to compensate for this It is also important to note that the 4 7KQ pull up resistor on Pin 5 is required for applicatio

6. With the dspFlash you can write many types of files into flash including LDR files which can be used to boot the processor There are specific configurations you must adhere to write bootable code to the flash For example if you are using a Blackfin BF 532 and a SPI flash you have to have a CS of PF2 and write with an offset of zero Bootable code must be written with an offset address of zero If you are using a SPI flash and a SHARC processor you also must bit reverse your data file This is required because of differences in the booting SPI configuration and normal SPI configurations This bit reversing can be done by checking the Bit box next to the applicable file s If you have already uploaded your code and must change this setting it is necessary to upload the file again It is important to note that when you are working with multiple files you do not have to bit reverse every file you are working with If you would like to bit reverse every file you are going to write you have to check every bit reverse box If your file is not intended to boot your processor your options are much more flexible There are dspFlash User Manual Page 9 many more chip select lines to choose from and you can make use of loading with offsets These files should be written in binary format and will be imaged bit for bit into flash Once you have chosen your data file and bit reversed it if need be the next step is to upload Uploading your data file

14. get but it doesn t boot properly Solution The most likely cause of this is writing the file improperly If you are using a processor with an SPI flash then bit reversing is necessary The other possible programming problem would be if the file were written with an offset Writing with offset is not a bootable configuration The other cause of this could be hardware If your hardware is not configured properly booting will not take place Most processors have specific requirements regarding which chip selects can be used and how the flash is connected In a parallel setup a certain memory select must be used Problem wrote something to the flash and now can t connect to my target even with an emulator Solution This probably happened because what was written to flash caused a processor core fault which results from bad code in the boot area of the flash This can be remedied by changing the boot configuration pins of your processor If these pins are tied directly to a supply and not through a pull up or pull down resistor then this method probably will not be possible This can also be remedied with an emulator and exceptional timing The trick to fixing the problem this way is to connect to your device between power up and boot This is possible on most processors however can be quite tricky Once the processor is booted and not faulted you should be able to erase the flash either with the emulator or with the dspFlash If you are going
15. he dspFlash programming process requires very little knowledge of the target processor and basically reduces the flash programming process to the push of a button The most demanding tasks to program a flash during production are reduced to opening a previously saved configuration file plugging a JTAG cable in properly and possibly resetting the target processor in the event of an error To actually configure the dspFlash you need to know the SPI or parallel flash configuration on the target board This includes the Chip Select configuration target processor and target flash models The dspFlash Windows application cannot generate a LDR or binary file directly but uses LDR or binary files that are created using VisualDSP or CrossCore Embedded Studio or other development environments If you do not have a background with these skills you may want to check out the Danville Signal website as well as the Analog Devices website for links to useful references Danville engineers are also available to discuss your application Early dspFlash Versions amp Updates The dspFlash was originally available in two versions a Basic version and the Deluxe version The Basic version has been discontinued for many years There were two hardware variants of the Basic version 1 amp 2 All Deluxe versions are type 2 You can identify the Basic version from the Deluxe by the color of the LEDs the Deluxe version uses red LEDs and the Basic version used Gre
