2019-04-29mtd-tests: nandbiterrs: Fix issue that just insert error at bit 7Xiaolei Li
The function insert_biterror should be designed to insert error at the first '1' bit starting at offset byte. But now, only bit 7 of each byte is checked, because checking mask is always 0x80. So, do right shift for checking mask after each checking to check the whole 8 bits of each bytes.

2018-03-05mtd: tests: check erase block count in page testStefan Agner
When there is only a single erase block, the cross erase test does not report sensible errors. Warn in case there is only a single erase block instead of executing the test. Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2017-11-22mtd: tests: Fix check on ebcnt in nandpagetestPaul HENRYS
If the number of erase blocks to use is not specified, ebcnt originally set to -1 leads the program to exit with: "Cannot run with less than two blocks." If the number of erase blocks to use is not specified and thus ebcnt is equal to -1, the expected behaviour is to perform the test on all the erase blocks of the mtd partition. This fixes the change introduced in 4458ad6481f60d9884925d5bc62a7954880d181b. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2017-11-03nandbiterrs: Fix copy & paste failDavid Oberhollenzer
When porting some of the mtd-tests to user space, some code was simplified. Among others, a while loop that iterates of page contents was replaced with a for loop, but the old increment was left in place, so every second byte was skipped. This patch removes the erroneous second increment. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2017-11-02Add no-return attribute to usage() style functionsDavid Oberhollenzer
A common pattern in command line processing is having a usage() function that prints out how to use the command line options and then terminates. The function is typically used inside a switch block for command line options like `-h' or unknown options. In a lot of places, the break keyword is omitted, because the function exits anyway. However, this triggers gcc warnings about implicit fall-through. Rather than adding a phony "/* fall-through */" this patch flags the usage() style function with a gcc attribute, indicating that they do not return and removes further superfluous break statements.

2017-08-24mtd-utils: tests: Avoid using less than two blocks in nandpagetestMiquel Raynal
Forbid the use of less than 2 eraseblocks in nandpagetest. It is obvious that the test cannot run on zero block, but it cannot run on only one block neither. The reason is: get_first_and_last_block() will return the same id for both the first and the last blocks. In erasecrosstest(), the logic is: - erase/write/read/verify first block - erase/write again first block - erase *last* block - read/verify first block When using only one block, 'first' refers to the same block as 'last', leading to erasing the block before reading it. Hence, the test would fail with no actual reason. Signed-off-by: Miquel Raynal <miquel.raynal@free-electrons.com> Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2017-07-03mtd-utils: tests: Add Erased Pages Bit Flip TestHarpreet Eli Sangha
Bit flip detection for written and erased pages tend to have different implementations. Where written pages are detected and corrected using ECC, erased pages are typically detected by ensuring that the number of zeros is less than a specified threshold. As such, it's necessary to have the 'nandbiterrs' test support the testing of written and erased pages. Bit flips in erased pages are emulated by rewriting the page in raw mode, to prevent the use of ECC.

2017-02-20mtd-utils: Fix format specifier definitions for off_t and loff_t.Torsten Fleischer
On 32bit systems (e.g. ARM) the size of off_t can be 4 byte and the size of loff_t 8 byte. This causes compiler warnings like the following: flash_erase.c: In function 'show_progress': flash_erase.c:56:22: warning: format '%llx' expects argument of type 'long long unsigned int', but argument 3 has type 'off_t {aka long int}' [-Wformat=] bareverbose(!quiet, "\rErasing %d Kibyte @ %"PRIxoff_t" -- %2i %% complete ", and an output like this: ~# flash_erase /dev/mtd2 0 1 Erasing 64 Kibyte @ 6400000000 -- 0 % complete ~# Since the size of off_t and loff_t can differ from each other, the printf format specifier should be determined separately for both. Further the format specifiers should be based directly on the size of the particular data type.

Basically a user space port of the mtd torture test kernel module. In addition to the block offset and count module parameters, the utility supports a block stride and can restore the block contents after test. In contrast to the kernel module, the torture test is implemented by the libmtd mtd_toruture function and thus doesn't allow for similarly fine grained options on diagnostics.
