Erase failed on Cortex M4

[Inspectron]

Today I have recieved the new nRF52 Development kit PCA10040. I did a update for the nRFgo Studio to version 1.21.2.3.

The softdevice s132_nrf52_2.0.0 will be flashed without errors. The template from SDK 11.0 will also be build without errors. But when I try to load the template on the chip, I will get this error:

Erase Failed! Error: Flash Download failed - "Cortex-M4"

Do I have to change the Target start adress for the IROM?

My is now:

IROM1:0x1B00 and size is 0x65000

IRAM1:20001F00 and size is 0x6100

Or what else is the reason for "Erase failed!"?

UPDATE:

It wont hit the err code. In the picture below, the breakpoint will never hit. If I set the breakpoint on SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, NULL); then it will hit the breakpoint. But I can not check what happens in the SOFTDEVICE_HANDLER_INIT function. Because SOFTDEVICE_HANDLER_INIT is defined in softdevice_handler.h. In this file I cant set a breakpoint and check the err code.

try full-erase chip before loading hex. some .hex files in SDK examples are merged with SD. That may block re-flashing.

I found the problem by my self. Just had to change IROM1 adress to 0x1C00. I have this information from the release note of the softdevice

Problem seems not to be solved. I'll get an error after SOFTDEVICE_HANDLER_INIT.

@inspectron: Could you post the error code?

[bjorn-spockeli]

If you are using the S132 v2.0 SoftDevice the ROM/RAM settings should be:

IROM1: Start: 0x1C000 Size: 0x64000

IRAM1: Start: 0x20002000 Size: 0xE000

The minimum required RAM is 0x13C8, but I have set it a bit higher. The actual requirement will depend upon the configuration chosen at sd_ble_enable() time. sd_ble_enable() will return * p_app_ram_base. indicating the minimum APP_RAM_BASE required by the SoftDevice for the configuration. Please refer the S13x_nRF5x_2.0.0 Migration Document, found here.

Update:

You need to check for new updates in the Packs Installer, see the screenshot below.
