[GitHub] [mynewt-core] vvzvlad opened a new issue #2152: board config file
for NRF52811
vvzvlad opened a new issue #2152: board config file for NRF52811
URL: https://github.com/apache/mynewt-core/issues/2152
I'm trying to run mynewt for my board with NRF52811(my board schematic [USB_dongle.PDF](https://github.com/apache/mynewt-core/files/4043225/USB_dongle.PDF) ). As far as I can see, this processor is supported but there is no board for it. I tried to create a board based on nordic_pca10040 but I must have made a mistake somewhere: my firmware does not run.
Му modifed board: [nrf_52811board.zip](https://github.com/apache/mynewt-core/files/4043204/nrf_52811board.zip)
Could you tell me what I have to do to run the code on NRF52811 processor?
As far as I can see, support for NRF52811 was added by a respectable @alvarop. Perhaps you can help me?

This does not seems like mynewt issue.
Anyway here are my thoughts.
*boot-nrf52xxaa.ld* should have correct ram size
```
MEMORY
{
FLASH (rx) : ORIGIN = 0x00000000, LENGTH = 0xC000
RAM (rwx) : ORIGIN = 0x20000000, LENGTH = 0x6000
}
```
*boot-nrf52xxaa.ld* has correct ram size but flash size should match slot 0 size
```
MEMORY
{
FLASH (rx) : ORIGIN = 0x0000C000, LENGTH = 0xD000
RAM (rwx) : ORIGIN = 0x20000000, LENGTH = 0x6000
}
```
Bootloader in most cases fits in 32KB instead of 48KB.
Blink led would better be pin 9 since pin 10 is also output from FTDI chip.
*bsp.h* should have correct ram size
```
#define RAM_SIZE 0x6000
```
