Posted on June 16, 2016 at 14:44Using an SPC564X, I'm trying to read how many bytes are in the BDRM (when in 4 byte buffer mode) on linflex3. I know it is possible on linflexd 0/1 using FIFO mode, but that isn't available on linflex2-9. The reason I...

Posted on September 29, 2015 at 16:48Hi We're trying to write a startup test for ECC detection using the EEGR register (table 524 of the reference manual RM0037). However it appears as if once a data inversion is forced (resulting in an IVOR 2 excep...

Posted on June 25, 2015 at 12:52Do ST have any data regarding Program/Data Flash write cycles and/or wear levelling for the SPC560B device(s)? I'd like to know if we have the option of using the Data Flash for built-in test logging on our SPC560B64.

Posted on January 29, 2015 at 13:56HiSection 6.1.1 of the SPC560x Reference Manual says that ''in order to successfully boot from flash memory, you must program two 32-bit fields into one of 5 possible boot blocks.''I have written 0x005A005A to addr...

Posted on January 12, 2015 at 12:58It appears that we cannot access internal flash on the SPC560B processor via the nexus debug interface. Do ST have any other recommendations regarding the ISP (in-system programming) of internal Flash for this fami...

Posted on May 12, 2016 at 18:53Michael I don't use SPC5Studio so I don't know what the equivalent is in that IDE. If you're using that (and presumably ST's O/S) I can't really help any further. I'd imagine though that the bootloader should be a sepa...

Posted on April 27, 2016 at 18:51Hi Michael You can use a linker definitions file to locate your bootloader at address 0 and your application at the next sector down (e.g. 0x18000). With a good RCHW (as I mentioned in the last post) the bootloader w...

Posted on April 06, 2016 at 18:15I don't work for ST or anything but we've done similar and we boot from Flash by loading the bootloader to address 0x00000000 after a valid RCHW (so the executable code starts at 0x00000008). If the SPC560B doesn't s...

Posted on March 23, 2016 at 18:17Follow on question: should an ECC error raise an IVOR 01 or an IVOR 02 exception? [EDIT] The IVOR 1 occurs during our IVOR 2 exception (because EE is cleared in the MSR) when we try to clear the ECC error, i.e. anoth...

Posted on October 27, 2015 at 16:53Thanks for the response. To recover the memory location needs to be written to and then read from to remove the error. Regards Kevin
