GUI Flash Tool programming external flash

[bamdadslr]

Hi,

I am using MCUXpresso to program a LPC4088 using Multilink Universal Rev C probe. I am using the GUI Flash tool to do the programming. I have two questions:

1. Does the Flash tool also program the external flash? it happens so fast that make me wonder about this. if the answer is No, then how I would program the external flash? This is the message in the console for your reference:

2. When trying to debug my code, I get errors on different routines that are defined as __attribute to those external flash areas. They cause different type of hard faults, like access violation or coprocessor access error. When I remove the __attribute, there is no error on those routines.  So it seems there is something wrong accessing the external flash. 

I would appreciate any help.

Hi!

For the first point, I am having the same problem with the GUI Flash Tool. And, be comparing my log to the one of collegues where it works, I see the following log (which you also have) that might explain the problem:

Unable to load libusb0.dll

The problem is that I don't know how to fix this error... I updated "GNU ARM PEMicro Interface Debugging Support" and even uninstalled and reinstalled MCUXpresso (I am using MCUXpresso IDE v11.6.1, which is also the version my collegue uses) but it did not help.

I posted this question directly related to this problem.

Thanks!

Hello,

If you want to download image to external flash, pay attention configure external flash memory ,

also choose flash driver "LPC40xx_SPIFI_GENERIC.cfx".
