Hello,
I'm working with µVision now. I have created a project and I want to load it on my evaluation board MCB4300 (LPC4350). If I click on "Build" I see "0 Error(s), 0 Warning(s)", but if I click on "Load" I get the following error message --> Error: Flash Download failed - "Cortex-M4".
In "Target Options" I completed:
Device: LPC4350-Cortex-M4 Utilities: Settings -> Flash Download -> Add -> LPC18xx/43xx S25FL032 SPIFI Utilities: Settings -> Debug -> Download Options -> Download to Flash (yes)
Where is the problem? I hope anyone can help me.
I added the following informations in the target options form MCB4300 - LPC4350:
Target Options:
Device: LPC4350 -> LPC4350: Cortex-M4
Target: IROM1: 0x1A000000 (Start) and 0x80000 (Size) (tick) IROM2: 0x1B000000 (Start) and 0x80000 (Size) IRAM1: 0x10000000 (Start) and 0x20000 (Size) (tick) IRAM2: 0x20000000 (Start) and 0x10000 (Size) Operating System: None
I can only add the following:
Utilities: Settings -> Flash Download -> Programming Algorithm -> Add
- LPC18xx/43xx S25FL032 SPIFI 4M (Flash Size) Ext. Flash SPI (Device Type) MDK Core (Origin - RC28F640J3x Dual Flash 16M Ext. Flash 32-bit MDK Core - S29GL064N Dual Flash 16M Ext. Flash 32-bit MDK Core
LPC18xx/43xx S25FL032 SPIFI Start: 0x14000000 Size: 0x00400000 RC28F640J3x Dual Flash Start: 0x00000000 Size: 0x01000000 S29GL064N Dual Flash Start: 0x1C000000 Size: 0x01000000
Utilities: Settings -> Flash Download -> RAM for Algorithm: 0x10000000 (Start), 0x1000 (Size)
I added LPC18xx/43xx S25FL032 SPIFI.
But it doesn't works. I get always the error message: "Error: Flash Download failed - "Cortex-M4""
And is that accompanied by any other errors/warnings in the transaction log, that might suggest why it failed?
No, there are no other errors or warnings.
Now I set the jumpers to SPIFI but nothing happened. The MCB4350 (LPC4350) has no internal flash, so must I configure in a other way. I'm working more than two days with this problem, and I can't load my program to MCB4350.
The examples for MCB4300 is only for LPC4357 and not for LPC4350, otherwise I will use them.
If I choose:
S29GL064N Dual Flash 16M Ext. Flash 32-bit MDK Core
I get the following error message:
Flash Timeout. Reset the Target and try it again.
and after that:
Error: Flash Download failed - "Cortex-M4"
The MCB4300 (LPC4350) has no internal flash, so I have to load my program in the RAM or external flash. S29GL064N is my external flash. So why I get this error messages now?
Maybe the reason is the configuration of the JTAG/SW port clock. Please configure it to 1MHz or higher. With slower clock speeds, the flash algorithms may time-out as the data are not delivered fast enough.
