Hello
I've encountered a problem when using 18F67K22 with the latest version of ds30loader. After making the necessary changes to the source files I program the mcu with the bootloader hex-file. Directly after reset of the mcu I press the 'Check for bl' button and it reports firmware version and mcu model. However, if I press the button again it times out.
If I press the 'Write'-button directly after resetting the mcu it reports bl ready and that it found my device but when it's about to start writing it times out.
Im using a baud rate of 115200 and checking the signals with my logic analysator the communication itself looks OK. Also verified hardware and speed setup with my main program where communication works flawless. But for some reason the bootloader stops responding after it sent one packet, the first one.
This is the ouput after pressing 'Write' with option 'Write flash':

- watchdog has been both activated and de-activated with same result as above.
- errata of this device states that in synchronous mode with high baudrates the data may become corrupt. However this bl works in async mode and my application itself has shoveled some hundred thousands packets with the same uart settings I specified in the bl. So that should be a non-issue here.
So far I have tried the usual stuff, change baudrate, fosc source, disable/enable PLL, triple checked the config words etc...
I will start a more indepth search to find this problem tonight. Will have to crosscheck the source files of this bl project with the sources I got working on another device to begin with and if there's no apparant error/difference I'll go with old "trig-led"
I could not see any difference (except mcu, and speed) between my current project source compared to the earlier source which is confirmed to work on a 25K20/22 mcu.
As I continued to measure and try different settings I added a bsf command in the user code space to the mcu pin (RD7) that controls a relay on my board. Basically I wanted to hear the click when the relay switches state as a reassurance that the user code space is executed without having to measure.
Anyways, the relay switches state upon startup and I continue by pressing the 'Write'-button.
What happens here is puzzling me, the relay drops again as if mcu gets reset. So I started measure the pins and sure enough, everytime I press 'Write' the mcu resets and gets stuck there. Only way to bring it out of that state is cycle power or MCLR-pin.
This does not occur with 'Check BL' and config STVREN On or Off makes no difference.
Your attached file, uart.inc, seems to do the trick. So far I can verify that 'Check bl' and 'Write' works like a charm. I will do some more tests with Reset commands, power off/mclr reset etc... But so far it is working great.
