Bootloader 4.14 issue with 18F2550 ?
Up to now all my Pinguino projects have been with 999 and Bootloader 2.12 and working fine on Windows7 Cool .

As some functions seems not worling on 2.12 (typicaly "OnTimer" interrupt) I have decided to move to 4.14.

I am suing 18F2550. I tried different frequency of the 4.14 bootloader (by the way, why there is so many) in 20MHz, but also 8MHz and even 4MHz; 
and:
None of these version give the blinking led.
Neither working when trying to download.

With the same HW configuration (PICKit2) and DIY board, it work on 2.12, but not at all on 4.14. Angry

In the mean time I will do my next project in 2.12.

I did probabely something wrong but what ? Angel

In the experiment I tried also the ICSP menu mode, but then the 18F2550 disapeared from the list (bug?). AN I got also message (no low frequency..) when compiling.

Hi,
I've compiled a bootloader for any possible crystal frequency supported because some people ask for them Wink .
Sorry to ask that but did you change the bootloader version from v2.x to v4.x in the Board Configuration Menu ?
It is easier to complain than it is to do, but it is better to do than it is to complain.

Regis,

Yes I did change the setting.

As I have a Crystal at 20MHz it means that I should use the file:
http://www.pinguino.cc/download/bootload...X20MHz.hex
Right ?

Is there a need to change the USB dll. Because, it is recognised as a "Regis" peripheral while the 2.x is a "Microship something"?

regards.

I'm not a Windows user but AFAIK this is not necessary.
However, v4.x is quite stable since 2 years so I wonder if it's still not a driver issue.
Do you get some error message from the IDE or just nothing ?
You might also try the stand-alone uploader (uploader8.py) from GitHub to see what it says.

Hi Regis,

I have the some problem, like druilhe. I have Win7 64bits, the bootloader is 4.14, the pinguino IDE the X.4, and the PIC is 18F2550. The bootloading doesn't work.

Best regards: Attila

Hi Attila,
Does this problem recently appeared ? Or you were using another OS or bootloader v2.x before ?
Your Pinguino acts as a USB Device only when it runs in bootloader mode. This one starts only when you press the reset button and it runs until you send your program to the PIC. When the bootloader is waiting for your program it should blink the built-in led at a high frequency. Do you see it blinking ?
Do you get some error message from the IDE ?
As I said to Druilhe, could you try the stand-alone uploader (uploader8.py) from GitHub to see what it says when you try to upload an hex file to your 2550 ?
If you have lsusb, do you see your Pinguino in the list ?

Regis,
 i have a windows 64 bit system with x1004 running and i have a 2550 with v4.14 working fine with no issues.
