Over the Air (OTA) is a technology that makes it easier for you to remotely update devices, such as IP cameras. A device can be upgraded with a full or differential package. A full package contains all content of a new system, and a differential package contains the differences between the old and new systems. Currently, only the full-package upgrade is supported.
Download the OpenSSL tool from the following website and install it on a Windows PC, and configure environment variables.
Access the tools\update_tools\update_pkg_tools directory, download the upgrade package making tool, and save it to a local directory, for example, D:\ota_tools.
Run Generate_public_private_key.bat in the ota_tools\key directory to generate Metis_PUBLIC.key, private.key, and public_arr.txt that contains public values, as shown in the following figure. Keep the private key properly.
Figure 1 Generating a Public/Private Key Pair
Use the array written in public_arr.txt as a substitute for g_pubKeyBuf in base\update\ota_lite\frameworks\source\verify\hota_verify.c of the OTA module.
Example array in public_arr.txt:
0x30,0x82,0x1,0xa,0x2,0x82,0x1,0x1,0x0,0xc7,0x8c,0xf3,0x91,0xa1,0x98,0xbf,0xb1,0x8c,

Example configuration for the public key of the OTA module:
#define PUBKEY_LENGTH 270
static uint8 g_pubKeyBuf[PUBKEY_LENGTH] = {
0x30, 0x82, 0x01, 0x0A, 0x02, 0x82, 0x01, 0x01, 0x00, 0xBF, 0xAA, 0xA5, 0xB3, 0xC2, 0x78, 0x5E,

(Optional) For Hi3518E V300 and Hi3516D V300 suites, further replace the array written in g_pub_key with that in public_arr.txt. The g_pub_key file is provided in device\hisilicon\third_party\uboot\u-boot-2020.01\product\hiupdate\verify\update_public_key.c of the U-Boot module.
Example configuration for the public key of the U-Boot module:
static unsigned char g_pub_key[PUBKEY_LEN] = {
0x30, 0x82, 0x01, 0x0A, 0x02, 0x82, 0x01, 0x01,
0x00, 0xBF, 0xAA, 0xA5, 0xB3, 0xC2, 0x78, 0x5E,
Save the files to be upgraded in the ota_tools\Components directory.

Table 1 Files to be upgraded
Open the packet_harmony.xml file in ota_tools\xml to modify compAddr as follows. Other items are reserved.
Example configuration for the component information:
<group name="own">
<list>
<component compAddr="rootfs" compId="0x0017" resType="0x05" isDelete="0x00" compType ="0x00" compVer="1.0">.\Components\rootfs_jffs2.img</component>
<component compAddr="kernel_A" compId="0x0018" resType="0x05" isDelete="0x00" compType ="0x00" compVer="1.1">.\Components\liteos.bin</component>
<component compAddr="data" compId="0x0019" resType="0x05" isDelete="0x00" compType ="0x00" compVer="1.2">.\Components\userfs_jffs2.img</component>
</list>
Configure the paths of private and public keys in packet_harmony.xml.
Example configuration for paths of private and public keys:
<encryption>
<privateKey type="der">.\key\private.key</privateKey>
<publicKey type="der">.\key\Metis_PUBLIC.key</publicKey>
</encryption>
Configure the product name and software version in ota_tools\VersionDefine.bat for anti-rollback.
Example configuration for the product name and software version:
set FILE_PRODUCT_NAME=Hisi
@rem Set the software version number to a string of no more than 16 characters.
set SOFTWARE_VER=OHOS_1.1
Run Make_Harmony_PKG.bat in the ota_tools directory to generate the Hisi_OpenHarmony 1.1.bin upgrade package. The upgrade package is signed using SHA-256 and RSA 2048 to ensure its integrity and validity.
Figure 3 Upgrade package making tool
Upload the Hisi_OpenHarmony 1.1.bin upgrade package to the vendor's OTA server.
The upgrade package is generated by following the instructions provided in Generating a Public/Private Key Pair and Generating an Upgrade Package.
Download the upgrade package for the current device, and then call the HotaInit function to initialize the OTA module.
Call the HotaWrite function to verify, parse, and write data streams into the device.
Call the HotaRestart function to restart the system.
If you want to cancel the upgrade, call the HotaCancel function.
Perform an OTA update using the upgrade package format and verification method provided by OpenHarmony.
int main(int argc, char **argv)
{
printf("this is update print!\r\n");
if (HotaInit(NULL, NULL) < 0) {
printf("ota update init fail!\r\n");
return -1;
}
int fd = open(OTA_PKG_FILE, O_RDWR, S_IRUSR | S_IWUSR);
if (fd < 0) {
printf("file open failed, fd = %d\r\n", fd);
(void)HotaCancel();
return -1;
}
int offset = 0;
int fileLen = lseek(fd, 0, SEEK_END);
int leftLen = fileLen;
while (leftLen > 0) {
if (lseek(fd, offset, SEEK_SET) < 0) {
close(fd);
printf("lseek fail!\r\n");
(void)HotaCancel();
return -1;
}
int tmpLen = leftLen >= READ_BUF_LEN ? READ_BUF_LEN : leftLen;
(void)memset_s(g_readBuf, READ_BUF_LEN, 0, READ_BUF_LEN);
if (read(fd, g_readBuf, tmpLen) < 0) {
close(fd);
printf("read fail!\r\n");
(void)HotaCancel();
return -1;
}
if (HotaWrite((unsigned char *)g_readBuf, offset, tmpLen) != 0) {
printf("ota write fail!\r\n");
close(fd);
(void)HotaCancel();
return -1;
}
offset += READ_BUF_LEN;
leftLen -= tmpLen;
}
close(fd);
printf("ota write finish!\r\n");
printf("device will reboot in 10s...\r\n");
sleep(10);
(void)HotaRestart();
return 0;
}
The upgrade package is generated in other ways instead of by referring to the preceding two sections.
Download the upgrade package for the current device, and then call the HotaInit function to initialize the OTA module.
Call the HotaSetPackageType function to set the package type to NOT_USE_DEFAULT_PKG.
Call the HotaWrite function to write data streams into the device.
Call the HotaRead function to read data. Vendors can choose to verify the data.
(Optional) Call the HotaSetBootSettings function to set the startup tag used for entering the U-Boot mode after restarting the system.
Call the HotaRestart function to restart the system.
If you want to cancel the upgrade, call the HotaCancel function.
Perform an OTA update using the upgrade package format and verification method not provided by OpenHarmony.
int main(int argc, char **argv)
{
printf("this is update print!\r\n");

printf("ota update init fail!\r\n");
(void)HotaCancel();
return -1;
}
(void)HotaSetPackageType(NOT_USE_DEFAULT_PKG);
int fd = open(OTA_PKG_FILE, O_RDWR, S_IRUSR | S_IWUSR);
if (fd < 0) {
printf("file open failed, fd = %d\r\n", fd);
(void)HotaCancel();
return -1;
}
int offset = 0;
int fileLen = lseek(fd, 0, SEEK_END);
int leftLen = fileLen;
while (leftLen > 0) {
if (lseek(fd, offset, SEEK_SET) < 0) {
close(fd);
printf("lseek fail!\r\n");
(void)HotaCancel();
return -1;
}
int tmpLen = leftLen >= READ_BUF_LEN ? READ_BUF_LEN : leftLen;
(void)memset_s(g_readBuf, READ_BUF_LEN, 0, READ_BUF_LEN);
if (read(fd, g_readBuf, tmpLen) < 0) {
close(fd);
printf("read fail!\r\n");
(void)HotaCancel();
return -1;
}
if (HotaWrite((unsigned char *)g_readBuf, offset, tmpLen) != 0) {
printf("ota write fail!\r\n");
close(fd);
(void)HotaCancel();
return -1;
}
offset += READ_BUF_LEN;
leftLen -= tmpLen;
}
close(fd);
printf("ota write finish!\r\n");
leftLen = fileLen;
while (leftLen > 0) {
int tmpLen = leftLen >= READ_BUF_LEN ? READ_BUF_LEN : leftLen;
(void)memset_s(g_readBuf, READ_BUF_LEN, 0, READ_BUF_LEN);
if (HotaRead(offset, READ_BUF_LEN, (unsigned char *)g_readBuf) != 0) {}
printf("ota write fail!\r\n");
(void)HotaCancel();
return -1;
}
/* do your verify and parse */
offset += READ_BUF_LEN;
leftLen -= tmpLen;
}
/* set your boot settings */
(void)HotaSetBootSettings();
printf("device will reboot in 10s...\r\n");
sleep(10);
(void)HotaRestart();
return 0;
}
Vendor applications call APIs of the OTA module to perform functions such as signature verification of the upgrade package, anti-rollback, burning and data flushing-to-disk. After the upgrade is complete, the system automatically restarts.
For Hi3518E V300 and Hi3516D V300 open-source suites, the value of LOCAL_VERSION needs to be modified for anti-rollback, for example, modifying ohos default 1.0 to ohos default 1.1. The macro LOCAL_VERSION is provided in device\hisilicon\third_party\uboot\u-boot-2020.01\product\hiupdate\ota_update\ota_local_info.c.
Example for modification of the local version:
const char *get_local_version(void)
{
#if defined(CONFIG_TARGET_HI3516EV200) || \
defined(CONFIG_TARGET_HI3516DV300) || \
defined(CONFIG_TARGET_HI3518EV300)
#define LOCAL_VERSION "ohos default 1.0" /* increase: default release version */
