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?
