EasyAVR problem
in [Embedded]

From: eden on 25 Jul 2005 07:00 Hi I am new to this group and new to embedded world. I both few months ago this board for beginers (link in English for the descendant EasyAVR2 http://www.mikroelektronika.co.yu/english/product/tools/etools.htm#3 with some addons, I couldn't find the link to my version, suppose it is outdated, this one have USB programmer, my has paralel port). The studio they ship with it was also very old 16bit Windows, I don't remember exectly the version, but from Atmel. Now, my problem was, I couldn't write anything into the chip (90S8515). This studio could connect to the board, read the EEPROM and program, but if I tried to erase or write something back, it was always failing, without any specific error. I tryied getting in contact with the support of this site, but they didn't bother too much answering back. All they could do was to reffer me to their poor users manual. But, I am sure I understanded it well, I am novice in embeded programming, but I am C/C++ programmer >5 years already, and I don't think there is much place for misunderstanding in their several pages user's manual. So, afer many sleepless nights, posting questions to several forums for Atmel AVR on the web, downloading different programs for transferring to the chip, aso... I put the board aside and forgot my little adventure in the embedded world. But, today I found this group, reading in comp.lang.c++.moderated the George Neuner posts there, so slight light of hope cross my mind. Is there any way I could check what's wrong with this board? As I mentioned earlier, I am novice in this field, I even don't have all the tools needed for mesurement the voltage or amperage, but I am willing to get them, if I could get good guidence. Thanks for any help. Goran
From: kunil on 25 Jul 2005 07:36 First thing to do : What kind of board that you use (EasyAVRv2 is just vendors name, not Atmel's official board) ? Do you have the schematic of it ? You should have it, because its your right as customer (you cant do anything without the board's schematic in your hand, thats why you MUST have it). Pls upload it somewhere, so I or someone can help. Thus, what is the name of software that you use to compile your firmware ? What's the name of software that you use to download (read/write) to EEPROM/Flash ? If you are using C/C++ to compile, probably it's GCC (alias WinAVR alias AVR-GCC), IAR, or CodeVision. CodeVision have ability to download your firmware from its IDE. What is your operating system ? You need to be specific so someone can help you. Since we are not there, we cant see the problem. -kunil eden wrote: > Hi > > I am new to this group and new to embedded world.

From: eden on 25 Jul 2005 08:03 At the moment, I am not at home, so I'll post all the details this evening around 20.00h (GMT+1). From the things I know: Yes, I think there was a JPG (or some other format) of the board shematic. I'll upload it somewhere. For the name of the software, I am not sure, but I'll put also this info later. I didn't use any compiler yet, my first try was to erase the chip and/or to upload precompiled bynaries that came with the board. I tried Win311 (the program is 16bit), Win95, Win98, Win2000, WinXP and Linux (Ubuntu). For windows versions I was using the supplied software from with the board. For Linux I downloaded opensource program, I'll check later the name. But, none was working. I get some suggestions at the time (few months ago) that maybe if I use WinXP, my ParallelPort could be not accessable, but this can't be the case 'couse I tried many OSs. Goran

Is there a jumper on the board that is currently set to prevent the EEPROM from being erased or written to? Does the chip that you're using have EEPROM, and is that EEPROM unlocked? ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |
