Hi ,
I'm writing one custom bootloader which sits on top of actual serial bootloader . when I pull boot0 to low my custom booloader should run instead of running main application. Please give me some suggestions for solving this.

This is a topic covered dozens of times, perhaps the answers would be salient for you as well. Review.
See IAP examples.

Hi
jogineni.madhu_babu
‌,There is an application note
: Programming an external Flash memory using the UART bootloader built-in STM32 microcontrollers. This application note is provided with an example firmware 'X-CUBE-EXTBOOT' showing how to program an external Quad-SPI flash memory using a developed user boot-code based on the internal UART bootloader protocol. The firmware 'http://www.st.com/en/embedded-software/x-cube-extboot.html
' could be downloaded from ST website. You may have a look at it. I think it will help you to develop your custom bootloader.
Khouloud.
