Fix: add missing new-line-escape in jffsX-utils Makemodule.am

2022-01-05T09:32:14+00:00

In commit a888044525, various header files that were added to the distribution tarball via EXTRA_DIST were instead added to the source lists of their respective programs instead. In the case of jffsX-utils, a missing escape for a new-line in the source list caused the include/linux/jffs2.h header to not be packged in the release tarball. This went undiscovered, as the system on which the release tarball was built, had the same header installed installed in the system include directory, so a `make distcheck` succeeded.

mtd-tests: use pages during readtest and stress

2021-12-06T00:47:02+00:00

Same fix as a2c6bbc ("mtd-tests: Read and write pages during speed tests") but applied to flash_readtest and flash_stress. Resolves failure of flash_readtest when subpages are present. The test reads a (sub)page followed by the entire OOB. Upon reaching the 2nd subpage, the OOB read fails because it is beyond the end of OOB.

mtd-tests: Read and write pages during speed tests

2021-10-13T11:16:49+00:00

The speed test does reads and writes of different sizes: - eraseblock - page - two pages At least this is the theory because, as opposed to the legacy kernel module doing the same measurement, the userspace tool uses the subpage size (hence accessing the same page 4, 8 or 16 times depending on the subpage setting). Of course if the controller does not support subpages, this issue is not visible. Use mtd.min_io_size instead for non-NOR devices in order to get the right bandwidth (at least one that fits the logs). Signed-off-by: Miquel Raynal Signed-off-by: David Oberhollenzer

Add ubiscan utility

2021-09-06T06:21:00+00:00

ubiscan will scan the PEBs in a specific MTD device and print a summary of the PEB erase counters and (optionally) details about each PEB's status. Example output: # ./ubiscan /dev/mtd6 Summary ========================================================= mtd : 6 type : nand size : 110362624 bytes (105.2 MiB) PEBs : 842 min I/O: 2048 bytes PEB erase counters ========================================================= valid : 834 empty : 0 corrupted: 0 alien : 0 bad : 8 Histogram ========================================================= from to count min avg max --------------------------------------------------------- 0 .. 9: 55 1 4 9 10 .. 99: 174 10 48 99 100 .. 999: 514 103 287 987 1000 .. 9999: 91 1004 1880 2251 10000 .. 99999: 0 0 0 0 100000 .. inf: 0 0 0 0 --------------------------------------------------------- Total : 834 1 392 2251 If the --verbose switch is given, ubiscan will print PEB details: # ./ubiscan --verbose /dev/mtd6 [... same output as before ...] Details ========================================================= PEB 0: 253 PEB 1: 1489 PEB 2: 1 PEB 3: 1 PEB 4: 1 PEB 5: 1 PEB 6: 1 PEB 7: 1 PEB 8: 1 PEB 9: 1 PEB 10: 1 ...

misc-utils: flashcp: Add new function that copy only different blocks

2021-06-12T15:17:15+00:00

- The original flashcp process is erase, write and verify all blocks in one time from file to device. This patch will add a function that only copy different block data from file to device. The function will compare blocks by block between file and device, then erase and write block data from file to device if found different block.

mtd-utils: Add flash_otp_erase

On some SPI NOR flashes you can actually erase the OTP region until its fully locked. Add a small utility for that. Signed-off-by: Michael Walle Signed-off-by: David Oberhollenzer
