Hard reset on qn9080

[talregev]

By mistake I write after the m_data  ORIGIN = 0x04000400, LENGTH = 0x0001FC00.

change to LENGTH = 0x0001FD114 at qn9080 DK-v1.2.

I want to perform hard reset to configure the chip to manufacture parameters (with working bootloader).

I try to flash one of the sdk example programs and the ide write me an error:

'MCUXpresso RedlinkMulti Driver v10.0 (Jun 22 2017 23:31:55 - crt_emu_cm_redlink build 272)
Reconnected to existing redlink server (PID 4294967295)

Failed on connect: Ee(36). Could not connect to core.
No connection to chip's debug port
error closing down debug session - Em(02). MEM-AP is not selecte'

Can you help me?

For future reference:

This thread was handled in an internal support request and the QN908x behavior appeared to be in a locked state where the flash can no longer be programmed.

How Do I unlock it?

I was able to unlock it using the QN908x_Programming_Tool.
