Hi everyone,

I develop a bare metal firmware for the system using iMX6S5.
It run directly to RAM memory without any problem with debugging through GDB J-Link, JTag and Eclipse.
However the requirement for the system is booting from SPI Flash. The system use the SPI Flash Spansion S25FL064L.
I use the J-Flash SPI V6.22f via J-Link to flash the binary but it can not detect the SPI flash.
The error message is:
Connecting ...
- Connecting via USB to J-Link device 0
- VTarget = 3.317V
- Read SPI Flash Id = 0x00 00 00
- ERROR: Failed to auto-detect SPI Flash.
- Failed to auto-detect SPI Flash.



I tried to change all the device but have the same result.
I checked in the document, the SPI Flash Spansion S25FL064L is supported by J-Flash SPI. Can some one here help me to figure it out ? Can I use the J-Flash to flash the binary to SPI Flash ?

Best Regards,
Nguyen.

Hi Nino,

Thanks for your reply.
My connection is indirect, so follow the link, the JLink SPI can not use.
However when I use the J-Flash, in the Project Settings/Flash, there is no SPI flash devices as I used. If I choose "Automatically detect flash memory", I have the error:

Do you have any idea about this issue? Can you suggest me the way that I can flash the binary to SPI Flash?
