Hello All,

Do you have the driver for S25HS512T flash chip without MTD drivers framework?

i.e. Just send and receive the cmds and data to SPI flash instead of MTD drivers framework. 

-Thanks.

Hello All,

For S25HS512T flash chip, Can we use the generic jedec driver (m25p80.c and spi-nor.c) files. 

Any changes required for this chip.

I want to raw access the flash chip using mtd_debug commands. 

I want to use the 256KB sectors, not 4KB sectors. I need the basic functionalities as Erase, write and read 

operations.

-Thanks. 

Hi~

One of customer asked the Part Information about Semper Flash Memory.

I  put some information. but I don't know other things.

Please guide for the information below

Thanks alot

Hello All,

Used the S25HS512T flash chip and drivers from Infineon. Not using the standard drivers from Linux (m25p80 and spi-nor)

The driver folder: Infineon-SPI_Flash_drivers_for_Linux_kernel_4.14.0-Software-v01_00-EN.zip

Using this driver, able to erase the sectors, write the sectors and read the sectors. 

After power  off and power on , again the read the data from flash. Here, it is failing. 

For example, I am trying to write the 1MB file. In power on time, i.e. after write operations and read it back. 

This works in proper. checked the data using md5sum. 

After power off and power on, read operation reads just 4KB data in proper and other values are garbage.

Could not find the reason for this? 

In above patch, they gave the flash_erase utils. But I use the standard utils. Whether this is the problem.

Please provide your inputs. 

If I give the reboot command in Linux, then again in cmd line, able to read the data in full manner. This works. 

-Thanks.

Hello All,

Tried the below cmds:

flash_erase /dev/mtdx 0 0 

It gives as success. After this, read the contents 

mtd_debug read /dev/mtdx 0 262144 file.txt

In this file, first 4KB, it has 0xff and other addresses, it has some garbage values. 

I could not find out the reason for this. 

Any inputs. 

Previously, Erase operation was working in properly, i.e. after erase, the memory values are 0xFF. For testing purpose, power off the board without giving the sync command. How to get back this to old state.  

Tried in multiple times, i.e. erase operations. But it is in same condition.

-Thanks.

Hi,

We use a '0P' speed option (Burst Frequency) part which is 66MHz version. The part number is S29WS256P0PBFW000

Can we directly replace this part with a 'AB' version which is a 104MHz version (part number S29WS256PABBFW000)?

In the datasheet, there are tables in page 70 about the wait state requirement but, there is no text explaining how to interpret these tables.

Thanks

Hello,

I would like to know the junction-case and junction-board thermal resistance.  I would also like to know the max allowable junction temperature.
thanks!

Hi,

I need to access to external memory S29GL512S with a STM32H7, I verify that HAL drivers from ST don't work with Infineon memories, because only be prepared to work with AMD, FUJITSU, INTEL, and SHARP. I'm sorry because I don't have soo much experience working with parallel memories.
Anyone work before with STM32 devices and memories from family S29GLxxxS.
What is the best way to solve my problem?

Best regards,
Luis Cristóvão
