Hello,
I'm using an ARM7 LPC2138 series and I'm having some troubles here. When I try to programing using Flash Magic Tool version 5.84.2259 I receive the following message:
'Operation Failed. Failed to autobaud - step 1.'
I've already checked pin 0.14 and it's connected to pull-down so its in low when I press the reset buttom.
Im using a 20.00Mhz oscillator and I've also checked it and it's really working.
I connected the board using a USB with 9600 baud-rate. I've tried 19200 and 4800 baud-rate and both failed.
The MAX232's pins are connected as follow:
o pin 14(T1OUT) - pin2 of the serial RS232 plug.
o pin 13(R1IN) - pin3 of the serial RS232 plug.
o pin 12(R1OUT) - pin21 (P0.1) of the LPC2138.
o pin 11(T1IN) - pin19 (P0.0) of the LPC2138.
It's everthing right in that connections?
I thought the problem could be in the MAX232 Transeiver, so I used a program (Docklight V1.9) to transmit anything throw the serial and it worked well.The MAX232 transmited the information to the microcontroller.
I dont know what else to do. I've tried a lot of tutorials and have already sent an email to nxp and followed theirs instructions, but it didnt work.
If someone knows what is the problem or some instructions to verify any errors, please tell me.
Thanks.
