I have isd51.dll ver 2.34. I would like to use an ISD with TI TUSB3210 processor (like standard 8052 derivate). And I've got an Error message from ISD51 Monitor Error: 'There was no reply from the target system!' I correctly set baudrate to 9600, tested both in simulator and hyperterminal as well described in ISD51.htm file. The function with 'A'character and output character work perfectlly. So I go back to simulator and try send HEX 0xA5 by sin=0xA5 command in simulator - it display 0xF7 followed by 6 hex values. => It seems that all work OK. But when I try it in Hyperterminal it does'not work. So I think that when Debugger send initial command - no response from 8052 by UART. Where should be an error ? Radim
>One thing which I could not get work properly was the I2C port. I did finally get it working, because an I2C connection to another processor (a PIC16F877) was a crucial part of my design. I referred to the TUSB3210 boot code, and did some signal logging with a digital CRO to finally crack it. (The TUSB3210 and TUSB4210 have very similar I2C hardware to the TUSB3200, but the error flag clears differently.)
