Re: [ECOS] How can I initial the flashs of sst29vfxxx and intel_strata at do_flash_init() ?

[Steven_cheng]

Hi Andrew,

    I  have gotten the flashv2 branch of eCos which supports
 multiple flash drivers at the same time. But I hope I can get the lastest
code from the
Anonymous CVS  and use the multiple flash drivers at the same time.
So I replace the directories "io\flash" and "devs\flash" with ones of
flashv2 branch.

But it has error messages:
undefined reference to "flash_unlock" in redboot_linux_exec.c 116/155
undefined reference to "flash_lock" in redboot_linux_exec.c 137/155

But I can not find flash_lick/flash_unlock in redboot_linux_exec.c .

Can you give me a suggestion ??

Thank you~

Steven Cheng

Each flash driver is split into two parts. There is a generic part and
a target specific part. You are probably missing the target specific
part. Take a look at packages/devs/flash/arm/aim711/current

Hi Andrew,

    I have updated my redboot package, then it is compiled OK~
There are two different flash type in my platform, one is intel 
CYGPKG_DEVS_FLASH_STRATA, and the other is 
CYGPKG_DEVS_FLASH_SST_39VFXXX. 
But I find it only CYGPKG_DEVS_FLASH_STRATA be initiated.
And I find that CYGHWR_IO_FLASH_DEVICE = 2.
The cyg_flashdevtab array only has strata information, how can I add
the sst information into cyg_flashdevtab[]??

Thank you~

I cannot find any reference either, so the linker is probably
confused.

Anyway, you have two options:

* update your redboot package to the flash_v2 branch.
* enabling the legacy flash API in the flash CDL options.

[Steven_cheng]

Dear Andrew,

    I have got the lastest packages from the anonymous CVS repository.
, but I still can not find the code which supports multiple flash drivers.
In the redboot\current\src\flash.c, it only initiates one flash driver.

Can you tell me the way in detail to get the flashv2 branch of eCos  ??

Thank you ~

I suggest you read the CVS documentation. It tells you all about
branches and how to access them.

The flash infrastructure in the eCos trunk only supports one flash
driver. You need to use the flashv2 branch of eCos which supports
multiple flash drivers at the same time.

[ECOS] How can I initial the flashs of sst29vfxxx and intel_strata at do_flash_init() ?

[Steven_cheng]

Hello All,

In my platform, it supports two flashs with sst29vfxxx and intel_strata.
When the cyg_start() of RedBoot calls the do_flash_init(),
it only calls the flash_hwr_init() of intel_strata but sst29vfxxx.
Then the redboot only disaply the flash info of intel_strata.
How can I initial the flashs of sst29vfxxx and intel_strata at
do_flash_init() ?

 -Thanks a lot !!
