I am writing a 2nd bootloader for my LPC812 that jumps to an application after downloading through the UART. To confirm the download was successful, I want to compare the CRC at the end of the application with a CRC I calculate with Chip_CRC_CRC8() found in chip_8xx.c. When I try to calculate the value of my application I get into the while loop and never exit. The size of my application is 0x1BFC bytes (application is contained in 0x2400 to 0x4000 in flash and last 4 bytes is CRC). Am I just running out of RAM during the loop so the processor locks up? Is there a limit to the size of the bytes parameter in Chip_CRC_CRC8() for the LPC812 due to the amount of available RAM?
Thanks for the help.
