Nor Flash Forum Discussions
Dear All,,,
I'm under reviewing about Cypress Serial Flash Memory / S25FL512S Series.
Pls, refer to the attached file. (the datasheet)
I can see the below on datasheet. (page 38)
I can not fully understand!
Could you please explain to me in more detail???
Thanks,
Show LessWe are using Cypress FFS for cypress S25FL164 chip.
We have an issue that, the files in the SPI chip are no longer accessible after period of time. We suspect some data could be corrupted (log file?)
Below are our investigations:
During power up, ionFS_zero_init() and ionFS_init() are successful.
But FFS Partition and Volume API functions such as ionFS_mount and ionFS_get_sectors always return IO Error (IONFS_EIO = -6).
The only workaround is to perform a low level full chip erase on the SPI Flash chip. After full chip erase, mount() function will return "File system was not formatted" (IONFS_ENOFMT = -33) and the format command is able create a volume and partition successfully.
Questions:
a) What is this IO Error and typically, what are the recommended steps to recover this issue?
b) Is it possible to force format a volume? --- ionFS_format function requires the number of available sectors and we retrieve using ionFS_get_sectors() function which will return IO Error (IONFS_EIO = -6).
Appreciate any feedback!
Show LessHi,
Regarding S25FL512SDSMFM010, if updating the following area of the Configuration register at every start-up,
do I have to consider the specification of endurance and data retention?
・ Latency Code
・ Puts the device into Quad I/O operation
I'd like to confirm whether this updating affects the number of writes.
Best regards, Shohei
Show LessHi,
We are using device: S70GL02GS in our design and need software to read ECC status code from specified pages on memory. Please redirect us to the existing driver code to do so.
Flash memory memory mapped to this address = 0x40000000
Show LessHello everyone.
I'm using S25FL127S serial NOR flash with PSoC 5LP MCU. I've been able to establish communication between the two.
I'm using the flash to write data which sometimes can be greater than the page length. When I try to read the same data, some part of it returns 0xFF which probably indicates that the address has reached its page limit. Is it possible to jump between the pages while writing & reading the data?
Please help, its urgent. Thanks in advance
Regards,
Vinay
Show LessI used s70fs01gs flash chip, can now read its id, but can not do other operations such as reading registers, if I want to operate it, need to do other initialization operations?
Error flag is erasing error when doing other operations,Read the data is 0xff,Or that no data is returned.
Used normal spi mode, Infineon tc297 chip
thanks .
Show LessCan you help me to find CY NOR flash which can replace below MICRON and MXIC parts? Please help to remark if CY parts can be the pin 2 pin replacement or any software migration job needed. VN Vendor P/N MICRON MT28EW512ABA1HJS-0SIT MXIC MX29GL512GUT2I-11G MICRON MT28EW128ABA1HJS-0SIT MXIC MX29GL128EHT2I-90G MICRON MT29F8G08ABACAWP-IT:C Thanks, Leon 8/20
Show LessCypress data sheet doesn't include any info on ESD Class of the Memory flash P/N S70FL01GSAGMFB010. Can anyone from Cypress engineering provide this info ?
