Other Parts Discussed in Thread: AM3517

Hi,

Why the PSP dont support boot from NOR flash while the AM3517 EVM do support boot from NOR flash?

Where can I get the PSP support for the NOR flash including tools and Doc's for flashing the NOR?

Thanks,

Ofer

Hi Eilon,

Somehow I missed to reply to this thread (its always better late than never).

We have created Wiki page describing the NOR flash support for AM3517 - http://processors.wiki.ti.com/index.php/AM35x-NOR-Flash-Support-ApplicationNote

I hope this would help you to understand the NOR boot status.

Thanks,

Vaibhav

Hi Vaibhav,

Could you check the following patch file ? It seems that it would not open X-loader-AM3517-NOR-Flash-Support.tar.gz‎

Also can you send me all NOR commands from UBOOT to flash the NOR?

Thanks,

Ofer

Hi Ofer,

Sorry for delayed response, actually I was on vacation so could not able to respond immediately.

I have updated the Application Notes page with valid patch tarball file, please let me know if you face any further issues with it. As far as NOR commands are concerned, use standard u-boot NOR flash commands. I have not saved the commands I used for testing, I just copied the command syntax below for your referance -

Writing to NOR Flash -

cp.b <RAM Addr> <NOR Addr> <size in bytes>

# cp.w 0x81000000 0x08000000 0x20000

Erasing NOR Flash -

erase <NOR Start Addr> <NOR End Addr>

# erase 0x08000000 0x0803FFFF


Thanks,
Vaibhav
