Hi Dirk,
Thanks for your resonse. I have just added into this thread beacuse both are
spansion flash.
my responses to your query:
1.am using u-boot_2099-08 U-boot. it came with imx6q saberlite board.
This is the 'old' U-Boot from Freescale which is modified heavily by
Freescale. Please ask the Freescale support for this.
Please try the recent mainline U-Boot, e.g.
http://git.denx.de/?p=u-boot/u-boot-imx.git;a=summary
2.NOR Flash is connected to WEIM Bus Chip select 0 and 16 bit Data
bus(D16:D31), I have done Weim Bus Mux Config in the Mx6q_saberlite_board .c
and also Chip select 0 initailization.
Hmm, I'm not totally sure, but if you boot from NOR, the correct mux
should already be done by the boot ROM code.
3. CONFIG_SYS_FLASH_BASE is WEIM_CSO_BASE_ADDR(0x08000000)
This looks correct.
Best regards
Dirk

In U-boot I am not seeing the support for Spansion S29GL512P NOR flash.
This chip is CFI compliant so I believe the common CFI driver should work
with this chip.
Does U-boot supports S29GL512P NOR flash or I have to implement the
functionality to support S29GL512P?
If anyone has tried with S29GL512P NOR flash please share the experiecne.
This chip is currently supported by the common CFI NOR FLASH driver. So it
should just work for your board as well.
Cheers,
Stefan

Hi Stefan,
I am Balaji. am using IMX6 base custom board. In my board am using S29GL01G
NOR Flash to srore u-boot and kernel. I understand from the data sheet this
NOR Flash is CFI based on. So i have added Configurations for CFI Flash driver.
Currently am loading the U-boot into DDR3 and able to excute U-boot test
commands. When i put flinfo , am getting "missing or unknow flash type" and
while loading the u-boot it is printing as " Unknown flash on BANK 1 - Size -
0MB". So am not sure what am missing here or i have to add anything extra in
teh config file. Please request you to check and provide your suggestion.
Just to be sure: Do you use the mainline U-Boot (u-boot.imx) or the
old Freescale one?
This thread talks about S29GL512P. You talk about S29GL01G?
Can you send us your flash/CFI configuration from the config file?
Which CONFIG_SYS_FLASH_BASE do you use?
Best regards
Dirk
