18F4620 [abandoned] - craig - 2011-02-22
Hi
I am having a problem when trying to get the DS30 Loader to communicated with a Pic 18F4620, I know that my RS232 comms is working as I have programmed other 16F devices.
Pic used 18F4620-E/P , 20 Mhz Crystal, Baud rate 115200, WDT Off, Low Power Disabled.
Initializing Download
searching for Bl............Time Out
I am pressing the reset switch connected to MCLR but it shows a time out.
I have gone into MPLAB IDE and set the configuration bits then exported the hex file out and used my programmer to load this into my Pic but when I use the DS30 loader to communicate with the Pic to load my hex file in to it I get the above mentioned problem.
I am using the latest version of DS30 & Gui loaded from the internet about a week ago.
Could someone Please help me and show me where I am going wrong ?
Regards
Craig

Hi Mikael
The version I Downloaded is as below:
Thanks for the Help so far.
What I did is to open the Firmware PIC18F file which opens in the MPLAB IDE and then change the Config and Device settings then save, Build ALL and then export the hex file out to be programmed with my Serial (P8076) Velleman Programmer.
Kind Regards
Craig

RE: 18F4620 - Mikael Gustavsson - 2011-02-24
Please provide a screenshot of your configs.
115200 wont work with 20MHz and without using BRG16.
Do have a working uart in your application?
Have you tried to first reset the device and then press download within 2 seconds?

Hi Mikael
Please see screen shot of configs. I do have a working Uart in my program and if I use a 16F887 in place of the 18F4620 and use the tiny boot loader to send data it works fine. What baud rate should I be using and what is the BRG16 ?
Regards
Craig
RE: 18F4620 - Mikael Gustavsson - 2011-02-24
9600 is good to start with. You can read about brg16 in the uart section in the data sheet.
If you use a 20MHz crystal you should set the oscillator config to HS and not Ext rc, see section 2 in the data sheet.

Hi Mikael
I have tried everything I can think of ! Please have a look at the various attached snapshots to see if I have made a mistake somewhere.
I see that there are advanced settings in the DS30 Gui should anything be set there? I did have a good look at the data sheet for this chip and I tested my UART on my board by putting a 16F887_20Mhz chip in the place of the 18F4620_20Mhz and it works with the boot loader so I know that my RS232 is working. ( In all the applications I am using an External 20Mhz Xtal)
There must be a setting or something that I have missed, Please have a look at the data and see what you think.
Regards
Craig

Hi Mikael
Please see the next two attachments they follow the previous five sent they would not fit on the same post.
PS. I have tried various board rates when using the DS30 Gui from 9600- 115200 but the results are all as per the attached Snapshots.[b]

How do you set up the uart on your working application?

Is the uart working in your application without the bootloader?

I am using Flow Control (RS232) in Proton to Communicate between 2 PIC's one is a 18F4620 and the other is a 16F887. I am using the Serin/Serout Commands set at 8 Bit No Parity True (Asynchronous) and this is working perfectly all the time.
I am only using the UART for the Boot loader using a separate Max 232 chip to communicate to either PIC when needed to download updated data to either PIC (by simply moving the TX & RX wires to to correct PIC). I know that it works because if I change the PIC18F4620 device to a 16F887 in the same application then my boot loader works on it, therefore I will have two 16F887 in the same circuit talking to each other.

RE: 18F4620 - Mikael Gustavsson - 2011-03-04
I give up, I still don't understand if you have a working serial communication between your PIC18 and the PC.
RE: 18F4620 - kvrbek - 2011-03-06
Hi, Craig
In attached *.zip file You have PIC18F4620_ds30loader.hex file
1) Program PIC18F4620_ds30loader.hex into Your PIC18F4620 (further mcu) with programmer. This *.hex file contain CONFIG fuses so you dont need to set fuses, eventually You have to turn ON option "Write CONFIG" (if that option exist in Your programmer software)
2) Be sure that mcu is running on 20MHz quartz.
3) Open ds30Loader app and select proper COM port, set baudrate of it to 19200
4) At this stage You mcu contain only bootloader and it is running it in loop all the time. So, you don't need to push reset button to initiate communication of ds30Loader app with mcu. Press Check BL button in ds30Loader and mcu has to give you the answer:
Found PIC18F4620 fw ver. 2.0.4
5) If you get answer above, thats it!
