Assert in at91rm9200_i2c.c

- Subject: [ECOS] Assert in at91rm9200_i2c.c
Hi all,
We've been developing an application on our own board which is based on the
AT91RM9200. The eCos config is closely based on that for the AT91RM9200-EK
and uses the I2C driver from that board to connect to an ADC (for monitoring
voltage, current, temp etc).
This basically appears to work fine but when I have eCos Asserts turned on I
very occasionally get the
following assertion:
ASSERT FAIL: <5>at91rm9200_i2c.c[101]at91rm9200_i2c_isr() I2C driver error:
OVRE without RXRDY
Could anybody give me some advice about what, from an application point of
view, could cause this sort of behaviour, or what sort of things I should be
thinking about?
Any assistance would be greatly appreciated,
regards,
Tim
PS: I am using version 2.0.43 of eCos.
