Wouldn't it be a good first step to replace the barebox udp API with the one picotcp provides? I mean I would expect that you replace only the network stack, not the network stack including the applications. If at some point we decide that the tftp implementation in picotcp is better than the one in barebox that would be the time to switch it. > > 2. with picotcp we can't easely use 'tftp' command with old syntax > (no $<current ethernet>.serverip anymore); > > 3. just now picotcp-based tftp file transfer is 5 times slower than > old realisation (partialy it is my bad, e.g. extra memory copy operation > is used for code simplification); An additional memcpy shouldn't make tftp 5 times slower. There must be something else.
