Seial Bootloader for MC9S08AC16

Question asked by Willy Rey on Aug 17, 2016


We are using the universal bootloader from AN2295, Version On the device MC9S08AC16 we are using the bootloader ASM Software from the very same AN2295 package. The device could be programmed well. Connecting to master Software we got the results as seen on the attached screenshot. It seems that the slave Software could not trim the busfrequency correct. the transmitted value of 0xB1 is away from 0xFC as required. We have a Resonator of 6.000 MHz on the board, so could we use this frequency instead, without selftrimming? Thank you vers much for your Support.

Best regards, Willy
