Porting S130 bootloader to NRF51822

[Andy]

Hello,

I'm pretty much new to NRF development and I'm having lots of questions trying to get a custom board to work with the provided BLE bootloader example in SDK 11.

I'm using GCC and most of the answers in this forum are using Keil I think. I see that I need to change the IROM and IRAM settings to match the ones for nrf51822_xxaa, but I have no idea where to do that. If somebody could point me out the basics I would be extremely grateful!

This is what I see in the linker file (some comments removed):

MEMORY
{
  FLASH (rx) : ORIGIN = 0x3C000, LENGTH = 0x3C00

  /** RAM Region for bootloader. This setting is suitable when used with s110, s120, s130, s310. */
  RAM (rwx) :  ORIGIN = 0x20002C00, LENGTH = 0x5380

  /** Location of non initialized RAM. Non initialized RAM is used for exchanging bond information
   *  from application to bootloader when using buttonluss DFU OTA. 
   */
  NOINIT (rwx) :  ORIGIN = 0x20007F80, LENGTH = 0x80
  BOOTLOADER_SETTINGS (rw) : ORIGIN = 0x0003FC00, LENGTH = 0x0400
  UICR_BOOTLOADER (r) : ORIGIN = 0x10001014, LENGTH = 0x04
}
