Writing Problem

Hi all,

I’m a new user :slight_smile: and I need some help please :).

Today I was testing my new H2138 board + JTAG with CrossWorks studio, after writing a small test program, I tried to upload it to the ARM flash, but only a few bytes are wrote correctly the other are always wrong, but the wrong bytes are always the same, that is, if it should be:

18 EF 24 31 it’s always: 18 FF 04 31

I’m using LPT port in EPP mode with the lowest clock possible and I get the same result on three different pc, is my board/jtag not functioning or it could be another problem? Thanx a lot!
