Raspberry pi booting problem

Thanks Clem for precious reply,

I need few things which i have in my existing hardware which  is Microcontroller based (St microcontroller STM32F103VET6 we are using), which is as follows:-

1.) Lcd (16*2 lines)   interfacing

2.) Spi

3.) six Adc (12 bit resolution)

4.) I2c

5.)Uart-2

6.)Usart-1

7.)approx 50 Gpios

How to modify my existing hardware which is controller based with raspberry pi processor , is their any way other then using ready made kit of it, why am saying this is because we wont be requiring several peripherals which comes in kit which is of credit card size, so that we can minimize costing of it.

Hi Roht,

With respect, if you're asking how to modify STM hardware project onto RPI and have not yet examined the interface capabilities

on the RPI, maybe you need to get the right person in your team to do this first? Then you'll know what interfaces are available

on the RPI, and then you guys need to decide how you will electronically manage any interfacing to achieve your needs.

Also you've not asked about the software - makes me think that you need to get someone to examine that too. Just a suggestion!

is their any way other then using ready made kit of it, why am saying this is because we wont be requiring several peripherals which comes in kit which is of credit card size, so that we can minimize costing of it.

If you're willing to pay, then customized RPI boards are offered by element14. (Minumum order of 5000 according to that page).

Then you can specify what you don't want. The process is documented at that link.

First of all thanks for reply,

U said i need some person in my team is for what purpose? I didnt get you? If u want a person in my team for replacing hardware and software then its myself who will do both u can discuss with me also.

Hi Roht,

I meant it sounds like you're asking very high level questions, so perhaps you're expecting someone else in your team to do the low-level work?

But if it is you who will be doing this, then have you checked what interfaces are available on the RPI?

I wanted to do check , could you please guide form where can i have its schematics ? so i can understand well.

It has been mentioned by Clem that full schematics are not available for the current models. For what is available, check out the first google hit for 'raspberry pi schematics'.

Easy to do!

You can check out what interfaces are available from the pinout diagram (again, google) and if you want you can read detail about the RPI ARM peripherals here (PDF).

Also, any reason why you didn't create a separate discussion? This has nothing to do with 'Raspberry Pi Booting Problem'.
