Author	Topic: C8051F86 flash and IDE issues
bugbuster1 New Member	posted July 29, 2010 11:40 AM Multiple flash-related issues with this chip. My firmware has successfully erased and written flash, but there are these issues: 1. With Silicon Labs IDE version 4.02, C8051F586 selected as type of chip, Tools/Erase code... behaves as follows: The first progress bar appears briefly then disappears. After a short pause, dialog appears saying, "Target failed to respond. System is being disconnected." 2. The chip is supposed to have Bank2 and 96k of flash. However, the Tools/Memory Fill/Code displays Enter Ending Address: B1:FDFF and will not accept a Bank 2 input. 3. My code that erases flash works, then on the next run, the MOVX A,@DPTR instruction causes the chip to reset. This is the first MOVX instruction to occur after setting FLKEY as directed and enabling flash erase with PSCTL bits 0 and 1. It works sometimes and resets sometimes. I haven't figured out yet how to predict the failure. We have had bootloader firmware in service for some years running on F122. I ported the bootloader from F122 to F586. It has worked perfectly on the F586, then stopped working. These problems on 3 different cards. The power supply is the same as on the old F122 card. The firmware has worked perfectly then failed. There are not many posts here about C8051Fxxx. Why is that? This chip is aimed at the auto industry, right? I once worked for a company that tried to break into the auto industry. They bet the store on a bid to become a Tier 1 supplier, and they lost--the whole company. IP: Logged

bugbuster1 New Member	posted July 29, 2010 04:54 PM More troubling than problems on any board are the IDE's incorrect support for the chip, still after all the years this chip has been in production. We are led to wonder if anyone uses this chip, and if so, what IDE they use, because no one has commented on these issues. We have been using SiLabs C8051Fxxx for more than six years. We have not seen problems like this before. IP: Logged
