'''A: I think its more reasonable that you have a bad serialport/cable, USB adapter? //Emil Larsson

Read all document befor you tke a conclusion; i write the flash with rs232;in terminal the board respond to any command but ONLY IN BOOT MODE (and in boot mode i can enter only loopback the board serial plug)

A bad serial adapter/cable (or broken ground in the cable) often seem to work for a few characters, but than fails in the middle of a bigger block.

If you can enter BOOT mode in 19200,8n1 and get answer for the following commands:

Than you are very likely to be able to reflash.**i can reflash but on verifying i get error (see up comment)

I'm thinking of a way to read/verify your bootloader and get verbose results.**i wait
