Issue ID: 1001775
Summary: Flash Safe service uses cyg_flash_lock &
cyg_flash_unlock despite they may be not available in
the configuration.
Product: eCos
Version: 1.2.5
Target: All
Architecture/Host HostOS: Win XP/7
OS:
Status: UNCONFIRMED
Severity: minor
Priority: normal
Component: Flash
Assignee: unassigned@bugs.ecos.sourceware.org
Reporter: vkirsan@mera.ru

I'm not sure if I have chosen the version of eCos and the component rightly.
I'm using eCosPro 3.1.25 and the component I'm reporting a bug on is Flash Safe
service (CYGPKG_FLASHSAFE).
Symptoms:
- Application binary fails to compile with the following messages from ld:
C:\eCosPro\workspace\ipTNA3i_config\ecos_install/lib\libtarget.a(services_flashsafe_flashsafe.o):
In function `cyg_flashsafe_commit':
c:/eCosPro/ecos-3.1.25/packages/services/flashsafe/v3_1_25/src/flashsafe.c:532:
undefined reference to `cyg_flash_lock'

collect2: ld returned 1 exit status
Speculations:
After a short examination of the documentation and the source code I found out
that my flash (am29xxxxx_v2 driver) doesn't support block locking (doesn't
implement CYGHWR_IO_FLASH_BLOCK_LOCKING interface). But Flash Safe, using this
facility of block locking, doesn't check if the implementation of the interface
is present or not.
Maybe there should be the additional dependency on
CYGHWR_IO_FLASH_BLOCK_LOCKING added in CYGPKG_FLASHSAFE so that the designer
could now from the beginning whether one can use Flash Safe or not with one's
flash memory?
