tiny bootloader has stopped working??

[epy]

Hi,

i am using tiny bootloader for pic16f877a pic. i am using windows 10 as well as windows 7.
i opened software and clicked on check device i got error as tiny bootloader has stopped working??
here is screenshot of that page.

how to resolve this problem?

@epy.

Really need a lot more information.
What version of the tlb+ exe?
What have you tried to resolve the issue?
What is your virus checker? Tried disabling it?
Are you an admin on the computer?
What are the policies applied to the computer?
Tried running as an administrator?
* What folder did you install into?

I have never seen a crash like and I have a forked build of the software. I have recompiled etc and I have not seen this issue.

I am using Tiny Multi Bootloader+ (v0.11.0) version.
Now i could able to open the software, it was MAX232's fault which was blown.

Controller : PIC16f887.
Crystal : 4MHZ
baud rate: 9600
I am using prolific's USB to serial cable.

But the problem is Software is not detecting PIC controller. I trried auto detect option but no luck.
I am using folllowing schematic.

and code is

    radix DEC
    LIST  F=INHX8M

    ; change these lines accordingly to your application    
#include "p16f887.inc"
IdTypePIC = 0x3C        ; must exists in "piccodes.ini"         
#define max_flash 0x2000    ; in WORDS, not bytes!!! (= 'max flash memory' from "piccodes.ini" divided by 2)

xtal EQU 4000000        ; you may also want to change: _HS_OSC _XT_OSC
baud EQU 9600           ; standard TinyBld baud rates: 115200 or 19200
    ; The above 5 lines can be changed and buid a bootloader for the desired frequency (and PIC type)

i gave 9600 because i am using 4 mhz instead of 8Mhz. So, Is it Okay? Or i should go with 19200 only.

[epy]

tried 19200 as well by doing following change in code

baud EQU 19200          ; standard TinyBld baud rates: 115200 or 19200

and following are the logs.

Check Device...
Open COM15 serial port at 19200bd
   Hardware RTS reseting Device
   Error: No Device Detected!!!
   Verify: - COM number
           - baud rate
           - if Device was reseted less than 1sec ago
             (do you need to check "RST Reset"?)
           - if TinyBootloader firmware is correctly
             programmed into Device
Close COM15 serial port

Switch to manual. Does that work?

[epy]

i didn't check this one. I think i will need hardware changes but not sure, which changes i will have to do.
Please suggest on same.

[epy]

which are the changes required in hardware? do i need to put switch in mclr or other port?
