MCP - Firmware upload - timeout waiting for START

[vit bernatik]

Hello, I tried to do DFU using MCP 3.10.0.14 and I'm getting the error:

"Error during firmware upload. Timeout while waiting for response for START DFU"

How do I increase timeout in MCP??

It seems to happen when I try to upload bigger firmware.

Thank you for tip. But I started from standard example (examples\dfu\bootloader\pca10040\dual_bank_ble_s132\arm5_no_packs\dfu_dual_bank_ble_s132_pca10040.uvprojx) and I did not touch the speed. It was set to fairly fast:

MIN_CONN_INTERVAL                    (uint16_t)(MSEC_TO_UNITS(15, UNIT_1_25_MS))           
MAX_CONN_INTERVAL                    (uint16_t)(MSEC_TO_UNITS(30, UNIT_1_25_MS))  

I tried to set 7.5 and 15. And the error is same.

Also it seems the error is before programming starts - so I assume what takes really long is erasing 360KB of Flash.. I think this is the bottle neck on FW side and it is in flash which is fixed...
