Can the code run from the flash?

[max]

It is possible to run my code from the flash? i need more space in the RAM for my buffer [8k]

[Håkon Alseth]

Code is normally located in flash. The variables it uses are then pushed on the stack (RAM). Globals are also located in a specific area in RAM.

You will not be able to make a buffer that's 8 kB when using one of our SoftDevices. Could you post a bit more detailed information about why you need a 8 kB buffer?

Cheers, Håkon

Hi, Thanks, I need read 10 burst of 675 bytes from some sensor and analyze the output and send it to my iPhone..

i use the s110 uart_ble_app .

if i create : static int16_t samples[675];
I have a linker errors

You'll have to split the data up in chunks to fit into the RAM area. You're about 17k over the RAM limit as of now. You could save the data to flash, then send that over the BLE link.

There is any documentation or sample project for writing to flash? Thanks

You should look at the pstorage documentation that came with the SDK. There are also a lot of good posts on this forum about pstorage.
