Hi team,
In our design we are using MSP firmware upgradation via I2C using Custom Bootloader. In that flash memory of MSP is divided into Dowload partition, App partition and App manager partition. The binary is sent from Master to the MSP430 which configured as slave and copied in to the download partition. Further the CRC is checked from the master and copied data , on matching of the crc its copied into the APP partition and similarly the CRC is checked. On successfull CRC matching the MCU goes for reboot which will loaded with the new firmware.
we are facing an issue in this, where the above mentioned steps is working fine when the image size is around 65Kb. when the image size exceeds, the copy from master to download area is fine and teh CRC is matching. but the copy from Dowload partition to APP partition is failing. This is happening only when the image size exceeds the 65kb, otherwise the copy is getting passed. what could be the reason behind this. Kindly help me here
