The file on DSP is lwip_sysboot_threadtype.c which is modified and serve as server.

While client is connected through VC++ using client.cpp

Files attached :- 1. lwip_sysboot_threadtype.c (file on DSP board)

2. client.cpp (running in VC++ envoirnment)

Thanks alot.

Can you provide the modified files so that we may try to replicate the problem here?

Thanks,

fwrite/ fputc error

analog@sgaur.hosted.jivesoftware.com — Thu, 02 Jul 2009 06:05:03 GMT

I am using BF537 ez kit lite.

I am implementing its example .............\Analog Devices\VisualDSP 5.0\Blackfin\Examples\ADSP-BF537 EZ-Kit Lite\Getting Started Examples\Part_2_1.

Simply i have defined a File pointer in it and read a file and store it in a dynamically created chracter array. Its ok.

The problem is when i save this file to the disk using fwrite, it writes the file but after some interval 4 bytes are re copied as shown in figure attached. Why these bytes are re-copied. If you save it at once or in chunks same problem occours.

I have checked the data of array its ok but i dont no why its is not writing the whole array truely into the file.

Figure:-

Two files are compared (actual file and saved file) which are in background.

Result of comparasion is in the file which is on forefront.
