eCAN: eCAN-A Boot Mode in Boot ROM

Revision(s) Affected

0, A on F2808, F2806, and F2801 silicon

Details

The eCAN-A boot mode in boot ROM does not work as intended. This is because the IDE and AME bits of the MSGID1 register are not initialized by the boot loader code. Since these bits can come up as 0 or a 1, frames transmitted by the host may not be received on the 2808.

Workaround(s)

This has been fixed in the B revision of the silicon. If the existing bootloader is to be used for developing an application, be certain that the IDE and AME bits are 0 before proceeding to use the eCAN-A mode of the bootloader to be sure that a standard identifier frame with an ID of 1 is received by the eCAN-A module.
