hello,   

      How to create a 2D array of size array[10000][10000]. I am getting the following error          unable to allocate space for sections/blocks with a total estimated minimum size of 0x66d14 bytes in <[0x20000000-0x20020000]> (total uncommitted space  .Thanks #stm32f

No kidding, the part you're using doesn't have 100MB of space to give you.

Thanks Clive for the prompt reply. 

One more Question how would I update the .DMA_BufferSize resistor as I update the PWM value by modifying the TIMx->CCRx resistor.Thanks Again.

I don't really understand the question, you can DMA_DeInit()/DMA_Init() to reconfigure a DMA transfer.

''how would I update the .DMA_BufferSize resistor (sic) as I update the PWM value by modifying the TIMx->CCRx resistor (sic)''

I think you mean re

g

ist

e

r?These are resistors:

Sorry for the trouble, I figured that out. 

Also one more thing I want to communicate to the terminal through USB, Do u have a sample code. I am using the STM32F4 discovery board.Thanks again...

I did port the VCP example to the STM32F4-DISCO
