The “tftpsrv.c” is used in my application. When I write the file to my application by tftp for many times, there is an error “TFTP Server Failure”. The error happens when writing the file in the 6th times. I set the break pointer to find the reason. I find that the source code run to the red part as follow shown. But if I read the file for many times, there is not any error. Can you help me find out the reason?
Remark:
- 1.My hardware : TWRK64F120M.The compiler is IAR7.4.
- 2.The MQX: Freescale_MQX_4_1_TWRK64F120M
- 3.The PC software is “Tftpd32 by Ph.Jounin”
- 4.The error happens in the source code of “tftpsrv.c”.
