Example two
The difference between the present embodiment and the first embodiment is that the effective system block in the system after power-on is judged;
the judgment of the effective system block in the system comprises the following steps:
a1, after receiving a power-on signal, judging whether an abnormal power-down signal exists, if so, acquiring the group number and the serial number of all the system blocks in the system space;
a2, grouping the system blocks according to the group numbers, and counting the number of the system blocks in each group;
a3, marking the group with larger number of the system blocks as an effective system block, and if the number of the system blocks in each group is the same, marking the group with larger number corresponding to the system block as an effective system block;
wherein, step S1 is preceded by: updating the group number of the system block;
when the system block is obtained from the system space, the method further comprises the following steps: incrementally numbering the system blocks obtained from the system space to obtain serial numbers, and adding the group number into the serial numbers, specifically:
referring to fig. 5, the present embodiment provides a system version management data structure;
designing a data structure SN with the size of 16 bits; wherein bit [15] SN1 represents the group number of the system block (sysblk) in the same batch, and the group number is updated (from 0 to 1 or from 1 to 0) every time the system block is upgraded; bit [14:0] SN0 is the version number of each system block, and the version number is incremented each time sysblk is brushed down from the system space; meanwhile, the whole SN is stored in raw data of nand page of the sysblk, and validity judgment can be carried out according to the SN number when the sysblk is read; please refer to fig. 6, which is a diagram illustrating SN updating; the system blocks in the system in the initial state are old-sysblk0 and old-sysblk1, and the corresponding group numbers and codes are respectively: SN 0X 0001 and SN 0X 0002; when updated, new-sysblk0, SN0 x 8003 and new-sysblk1 and SN0 x 8004 are obtained, and when updated, new-sysblk0, SN0 x 0005 and new-sysblk1, SN0 x 0006 and so on are obtained;
referring to fig. 7, the present embodiment provides a specific scenario for determining valid system blocks in the system:
a1, if abnormal power failure exists after receiving the power-on signal, carrying out a validity judgment step through a validity judgment entry, and reading and recording SN of all system blocks; meanwhile, whether tmpblk0/1 exists in the system block or not is judged, and if yes, the tmpblk0/1 is released;
a2, grouping the system blocks according to the group numbers in the SNs of the system blocks to obtain group0/1, and counting the number of the system blocks in group0 and group 1;
a3, marking the group with the larger number of the system blocks as an effective system block, if the number of the system blocks in the group0 and the group1 is the same (for example, 2: 2), marking the group with the larger number corresponding to the system block as an effective system block (namely, comparing bit [14:0] of SN), exiting the effectiveness judgment, and entering the system;
referring to fig. 4, after the system upgrade method is adopted, normal startup can be performed in various problem scenarios:
scene 1: in the process of issuing fw.bin (i.e., in the process of executing step S3), if data jump occurs, the device identifies the data jump when checking tmpblk0 (i.e., determining whether the data is abnormal in S4), so that device abnormality is not caused;
scene 2: the device loses power under the condition of brushing a certain 16K (namely in the process of executing the step S3), in this case, the upgrade process will be exited, but because the original system block is still valid, after the valid data block is judged after being electrified, the original system block can be marked as the valid data block, so that the device will not be abnormal;
scene 3: the equipment is powered off when the tmpblk1 data is sorted, in this case, the upgrading process is exited, but after the validity judgment is passed, the original system block is still set as the valid system block of the current system, so that the equipment abnormality cannot be caused;
scene 4: when the device fails to update the new fw bin successfully before or during the new blk0 is refreshed, the old system block is erased and released only when both the new blks are successfully refreshed and verified, and therefore the original system block is still set as the effective system block of the current system after the validity judgment is passed, and the device is not abnormal;
scene 5: when the power failure occurs before or during the device is refreshed in newblk1, 3 system blocks including 2 old system blocks and 1 new system block are generated after the device is powered on again, after validity judgment is performed, the 1 new system block is erased, and the original 2 system blocks are still valid, so that the device is not abnormal;
scene 6: when the device is powered down after the newblk1 is refreshed, before the old system blocks are released, 4 system blocks including 2 old system blocks and 2 new system blocks are available after the device is powered up again, and after the validity judgment is performed, the 2 old system blocks are erased, the 2 new system blocks are valid, and the device is not abnormal.

when the system block is obtained from the system space, the method further comprises the following steps:
carrying out incremental numbering on the system blocks obtained from the system space to obtain a serial number, and adding the group number into the serial number;
after receiving a power-on signal, judging whether an abnormal power-down signal exists or not, if so, acquiring the group numbers and serial numbers of all the system blocks in the system space;
grouping the system blocks according to the group numbers, and counting the number of the system blocks in each group;
marking the group with the larger number of the system blocks as a valid system block;
if the number of the system blocks in each group is the same, marking the group with the large number corresponding to the system block as an effective system block;
judging whether the system data to be upgraded in the first system block is abnormal, if not, acquiring a second system block corresponding to the size of the storage space from the system space according to the data volume of the system to be upgraded comprises the following steps:
judging whether the system data to be upgraded in the first system block is abnormal or not, if not, judging whether the storage format of the system data to be upgraded is consistent with the storage format required by the system block or not, and if not, acquiring a third system block with the corresponding storage space size from the system space according to the data volume of the system data to be upgraded; transmitting the system data to be upgraded in the first system block to the third system block for format conversion and then transmitting the system data to be upgraded in the second system block;
and if so, executing the step of acquiring a second system block corresponding to the size of the storage space from the system space according to the system data volume to be upgraded.
5. A computer-readable storage medium, on which a computer program is stored which, when being executed by a processor, carries out the steps of a method for system block upgrade as claimed in any one of claims 1 to 3.
6. An electronic device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, wherein the processor implements the steps of a method of system block upgrade as claimed in any one of claims 1 to 3 when executing the computer program.
