xcore-200 DFU DFLASH_MAX_UPGRADE_SIZE and issues
Posted: Fri Jul 30, 2021 10:26 am
Hi,
We're having a few issues with flaky DFU operation and would like some information regarding the DFLASH_MAX_UPGRADE_SIZE setting in the Makefile. Other DFU posts mention to check this setting but we're not sure what to set it too. Our part is a IS25LP08D 8 MBit part and the default Makefile settings are DFLASH_MAX_UPGRADE_SIZE=192*1024. Our DFU bin is around 70k. Problem we're actually experiencing is if the image is flashed on to the board without DFU its fine, however if it's DFU'd on then only 20% of the time it works. The odd thing is that a few extra cleans and rebuilds it works again..
Any help would be appreciated.
Cheers.
