Atmega128 -
Author Unknown

This document pertains to the Black ATMEGA's( Official OMEGA-EFA's ) and the 
Blue wafer ATMEGA's with a switch. 

BLUE WAFER WITHOUT SWITCH 
========================= 
If you have a Blue wafer without a switch. You will be required to make a 
modification to the board: Adding a two-way switch. The two-way switch is attached 
in the following manner. Place the board in front of you so the ATMEGA chip is 
farthest from you. Note where the wire or 000 is placed on the board, and remove it. 
The top end of this wire goes to left side of switch, now to the right is a blank 
soldering pad, connect this pad to right side of switch. Now connect the middle of 
the switch to the bottom pad where the wire came off of. 

TROUBLE-SHOOTING 
================ 
1. "Failed to Enter program mode" Message from JeepersDx210 
1. ATMEGA128 Connection: 
1.1 Verify the card is inserted into programmer correctly. 
1.2 Insert the ATMEGA128 with a Smart Card or business cards in programmer. 
1.3 Verify ATMEGA is rectangular, no external bits attached to board. 

2. Voltage Problem: 
2.1 Try using a gender changer instead of a cable for the programmer. 
2.2 Try using a different computer ( no Compaq's, Dell's, HP's these are 
known to cause problems ). If works create a external power supply 
for programmer. 

3. Incorrect Jumper(Black ATMEGA) or Switch(Blue ATMEGA) Setting: 
3.1 For Black ATMEGA program with Jumper ON. 
3.2 For Blue ATMEGA program with switch away from ATMEGA128 chip. 

4. ATMEGA Programmed at improper crystal frequency. This is bad as it may render the ATMEGA128 chip useless until unlocked. 
4.1 Verify the crystal frequency by looking at the silver item on the ATMEGA 
board and verify that are your using the correct board type 
( i.e.; ATmega128@##.####MHz). 
4.2 See 5.1 

5. ATMEGA128 Locked 
5.1 Start JeepersDx and select ATMEL -> ATmega128 Erase Flash/EEPROM, then 
program at proper board frequency of crystal. If no go, look into 1.2 more. 
Please note: This requires a known computer that can write and ATMEGA board. 

6. "Smart Card not inserted Correctly Message" when ATMEGA in receiver. 
6.1 Incorrect Programming: 
6.2 Verify you set Board type as ATmega128@18.0000MHz for Black ATMEGA and 
ATMEGA@18.4320MHz for Blue ATMEGA. 
6.3 Jumper or Switch in Wrong Position: 
6.4 Make sure jumper is off on Black ATMEGA while in Receiver. 
6.5 Make sure switch is towards ATMEGA128 chip on Blue ATMEGA's. 

7. Capacitors Blown: 
7.1 Remove C1 and C2 from ATMEGA board, reprogram and see if works. 
7.2 Preview Channels Only, All others Black Screen. 
7.3 Initial Wait for video: 
7.4 Can take from 20 seconds to 2 minutes for initial video to appear upon 
power on of receiver. 

8. Wrong Keys 
8.1 Verify Key0 and Key1 are correct. 
8.2 Verify proper boxkeys are being used. 
8.3 Static 
8.4 Program ATMEGA as normal, then insert in IRD for 5 minutes trying to watch a 
black channel. Then connect ATMEGA back to computer, and Hit Actions -> Verify 
EEPROM, then Actions -> Verify Program. 
8.5 If errors: 
Reprogram ATMEGA, unplug power from IRD and satellite feed, insert ATMEGA, 
wait 1 minute, then plug in power and satellite feed. 
8.6 If no errors: 
Reprogram ATMEGA, select ATMEL -> ATmega128 and Lock/Fuse Settings, select 
yes to continue, remove check mark from M103C in Fuse Extended section, then 
remove jumper(black ATMEGA) or move switch(blue ATMEGA) towards ATMEGA128 
chip, then hit write. 

9. Bad ATMEGA128 chip 
9.1 Program ATMEGA as normal, and Hit Actions -> Verify EEPROM, then Actions -> Verify 
Program. If error and you have tried on many different computers, most likely 
bad chip. 

10. Picture will freeze in few min to few hours. 
10.1. Wrong Lock/Fuse bit. 
10.2 Up/down channel will work again. 
10.3 *** Don't fool with other setting, do this at your own risk*** 
Remove jumper from Black ATMEGA or move switch towards ATMEGA128 chip on Blue 
ATMEGA. After program ATMEGA as normal, select ->Atmel,->Atmeg128-> lock/fuse 
settings. Click on "CKOPT" to de-select. Click on write 

11. Incorrect crystal used on ATMEGA. 
11.1 Verify you are using either a 18mhz or 18.43mhz crystal on ATMEGA. 

12. ATMEGA programmed at board type ATMEGA128 only. 
12.1 Program at proper crystal frequency and verify switch(Blue ATMEGA) is towards 
ATMEGA128 chip or Jumper(Black ATMEGA) is off. 
12.2. Software catching up 
12.3 Blackouts occur when the stream is out of whack with the software and the 
software needs to catch up with the proper sequence of stream, usually can take 
up to 45 seconds. 

13. Video for few minutes/hours/day then black screen. 
13.1 Programmed at incorrect crystal frequency: 
13.2 Program at proper crystal speed ( see 2.1.1 ) 
13.3 Keys change: 
13.4 Program ATMEGA with new keys: Connect ATMEGA to computer, start JeepersDX, hit 
get under keys section, then hit write. Insert ATMEGA back into receiver. 

14. "Blacked out in the area" message while trying to watch a channel. 
14.1 Wrong blackout string 
14.2 Use default blackout string of "00 00 B4 7F 7F 7F 7F 7F 7F 7F 7F 7F 7F 7F 7F". 
14.3 Channel guide: 
14.4 Do not use channel guide to get into channel, type in channel # directly, if still 
same message press channel up then channel down. 

15. Channels Missing in guide. 
15.1. Wrong tiers: 
15.2 Use default tier settings from JeepersDX210.After program ATMEGA as normal, select ->Atmel,->Atmeg128-> lock/fuse
