Abstract: To solve the problem that traditional GPRS‐based wireless remote code update loses a large amount of data collected , a design scheme that receiving the remote code segmentally and updating it concentratedly was proposed by analyzing the boot‐loader mechanism .Based on Arm Cortex M4 kernel ,combined with GPRS transparent transmission technology ,the design re‐lied on the user application to receive remote code segmentally ,and then the code was stored in the SD card and read by a special bootloader to complete the code update .The shielded data acquisition time was reduced during the code updating process .Results of test show that the scheme can achieve code update without data loss below 2 HZ frequency .
