J-Link failing to (re)program HyperFlash on RT1050 EVK

[ryanshuttlewort]

Hello I am using MCUXpresso IDE, version v10.1.0 [Build 589] [2017-11-14] with an MIMXRT1050-EVK SDK, version  2.3.0 (2017-11-16).  I am finding that I can only occasionally (re)program HyperFlash via J-Link, see "Verify failed" in the dump below.  When this happens I've had to resort to bulk erasing and then re-programming via the OpenSDA interface which will not be an option in our final product given that it will have J-Link only. 

Any suggestions as why this might be happening and how to avoid it would be appreciated.

Thanks.

We're of the understanding Segger is already working on RT1050 flash support.

Thanks and regards,

MCUXpresso Support

[srinivas_chilaka]

Please let me know when it will be ready? Do we have timeline for it?

[GottiLuca]

Seggere has just added support for both HyperFlash and QSPI .

I've personally tested with my Segger JLink on the EVK1050 with HyperFlash and it runs correctly.

See : Release notes for the J-Link Software and Documentation Pack  

( Version V6.32 (2018-04-20))

[lpcxpresso_supp]

From the point of view of flash programming, the on board OpenSDA debug probe can have the same capabilities as an external debug probe (albeit likely the OpenSDA variant will program more slowly).

These capabilities however are determined by the firmware type (which determines which debug solution LinkServer, P&E or SEGGER). So:

OpenSDA programmed with JLink firmware can have the same capabilities as an external J-Link probe

OpenSDA programmed with DAP-Link will have the same capabilities as an LPC-Link2 (programmed with CMSIS-DAP/LinkServer) firmware etc.

Note: external debug probes may have many more features/improvements but these will not change whether flash programming is supported (unless

Note also: LPC-Link2 can be programmed with SEGGER J-Link firmware, in which case it will have the capabilities of SEGGER's debug solution.

The above is a general statement, and excludes advanced debug features or artificial restrictions that could potentially be included.

Yours,

Hi MCUXpresso IDE Support,

I am also trying to get the JLink working with the RT1050 series external flash.

Is there any project in the works at NXP to create/release a Flash Loader for J-Link for the RT1050 devices? From reading the Segger JLink documention (Chapter 10, UM08001 JLink Manual and Adding Support for New Devices - SEGGER - Support Wiki ) it seems it is possible for NXP to create this flash loader (possibly just by modifying the existing MCPXpresso cfx flash loader) and submit to Segger for inclusion in their driver.

thanks,

Craig

Hi Ryan,

I do not believe SEGGER J-Link currently supports programming the Hyperflash within the RT1050, rather it treats this memory region as RAM and so the write fails to verify.  If a flash operation were being performed you would see something similar to below within the log:

...
Resetting target
Downloading 13744 bytes @ address 0x60000000 - Verified OK
Downloading 12 bytes @ address 0x600035B0 - Verified OK
J-Link: Flash download: Bank 0 @ 0x60000000: 1 range affected (16384 bytes)
J-Link: Flash download: Total time needed: 0.211s (Prepare: 0.026s, Compare: 0.005s, Erase: 0.025s, Program: 0.147s, Verify: 0.000s, Restore: 0.004s)

When they do however, MCUXPresso IDE can be switched to a newly installed J-Link version via:

Preferences -> MCUXpresso IDE -> J-Link Options -> Restore Defaults

This will force a scan for installed versions and an update to the base version to use.

Yours,

So just to be very clear.  Are the OpenSDA interface and the MfgTool the only way to program HyperFlash and QSPI Flash or would the LCP-Link in the previous suggestion also work?

Thanks.

[ryanshuttlewort]

Ok, thanks.  I think I was getting confused by a previous hello_world_xip application programmed via OpenSDA.  The J0Link went through the motions of programming and verified memory correctly because the image was the same as that already in memory.

Hi Ryan,

Not sure what this is causing, but maybe you can enable/post the GDB traces (see Board Bring-Up Tips, GDB Logs and Traces in Eclipse | MCU on Eclipse)?

As for erasing the Hyperflash: If you don't have the OpenSDA (aka DAPLink), then you could use the LPC-Link2 instead. I have used it that way sucessfully with my board (see MCUXpresso IDE V10.1.0 with i.MX RT1052 Crossover Processor | MCU on Eclipse ). The LPC-Link2 is $20 only (LPC-Link2|NXP ) it it is always good to have one at hand.

I hope this helps,

Erich

Thanks Erich, I had seen the LPC-Link mentioned but wasn't quite sure were it fit in.
