Please refer to attachments for a letter of authorization from Radisys and a list of part numbers. Please note that Radisys might not purchase directly from your company but via a supplier or distributor. In addition, you might need to collect material or compliance documents from your suppliers such as raw material manufacturers to fulfill your customer’s requests. Your support to your end customer is appreciated.

One of your parts that they are requesting data for is:

Can you please provide the following environmental compliance data for these parts:

• RoHS 2(2015/863/EU and 2011/65/EU) Certificate of Compliance (CoC). Directive 2015/863/EU, published June 4, 2015, amends RoHS 2 2011/65/EU to include 4 additional restricted substances.
• REACH Declaration or SVHC Certificate. If a product contains any SVHC or Substances of REACH - Annex XIV, please provide the substance name and concentration, as well as future plan to eliminate its use.
• If reportable SVHCs are identified, Substances of Concern In articles as such or in complex objects (Products) (SCIP – per Waste Framework Directive 2008/98/EC, amended by Directive (EU) 2018/851).
• Full Material Disclosure (FMD), MSDS or similar document in your standard format if available
• Lifecycle Status.
• Contain any CA Prop65 (whether the part contains any CA Prop65 Substance that does not meet the Safe Harbor requirements.) (Yes, No). If it does, please the substance name and its CAS number, the type of toxicity (Cancer or reproductive toxicity) and the location of the substance.

If you cannot recognize a part or it's incorrect, please indicate such in your feedback.

Please respond as soon as possible or provide an expected date of completion and we will follow up. We may contact you if any clarification is needed. Radisys is committed to providing its customers with products that meet the highest standards of innovation, performance and environmental safety and expects your timely response

Hi,

I'm trying to get the FAT FS implementation running on a system that contains the nRF52840 and the S25FS128S.

I can see that data is being written to the S25FS128S but I can't get beyond the writing and mounting of the file system. I am starting to suspect the issue might be with the non-uniform memory sector layout at the beginning of the flash memory.

I have the memory chip in 32bit addressing mode and I am trying to get it out of the standard hybrid sector mode with the following operation:

//test for non hybrid sectors
uint32_t reg_adr = 0x000004;
uint32_t status = 0;
uint32_t temp;

uint8_t location[5], rdBuf[2];

//location[0] = 0x06; /* Write enable. */
cinstr_cfg2.opcode = 0x06;
cinstr_cfg2.length = NRF_QSPI_CINSTR_LEN_1B;

status = nrf_drv_qspi_cinstr_xfer(&cinstr_cfg2, NULL, NULL);//CyU3PSpiTransferWords (location, 1, 0, 0);

rdBuf[0] = 0x8;

cinstr_cfg2.opcode = 0x71; /* Sector erase. */
cinstr_cfg2.length = NRF_QSPI_CINSTR_LEN_6B;
temp = reg_adr;

location[0] = (temp >> 16) & 0xFF;

location[1] = (temp >> 16) & 0xFF;

location[2] = (temp >> 😎 & 0xFF;

location[3] = temp & 0xFF;

location[4] = 0x08;


status = nrf_drv_qspi_cinstr_xfer(&cinstr_cfg2, location, NULL);//CyU3PSpiTransferWords (location, 5, 0, 0);

nrf_delay_ms(250);

So basically my question is two fold:

1. Is it possible that the hybrid sector layout is what is causing the issues with the FAT FS (It works perfectly well on the flash chip that comes with their development board)
2. Is the piece of code above the correct way to put the flash memory in uniform sector mode or am I missing any steps? (eg do I need to reset the chip after or something)

Thanks In advance,

Michiel

In production floor I want to program the S29GL064N90FFI020; then reflow the part onto the board. Is there a tool that I can program the part with? 

I have a S25FL128S/S25FL256S device, and I was going to leverage the 16 lowest address bytes from the OTP address space as a random number since it states:  (part 7.4 in https://www.cypress.com/file/448601/download)

“In the 32-byte region starting at address zero:

■ The 16 lowest address bytes are programmed by Cypress with a 128-bit random number. Only Cypress is able to program these bytes.

■ The next 4 higher address bytes (OTP Lock Bytes) are used to provide one bit per OTP region to permanently protect each

■ region from programming. The bytes are erased when shipped from Cypress. After an OTP region is programmed, it can be locked to prevent further programming, by programming the related protection bit in the OTP Lock Bytes.

■ The next higher 12 bytes of the lowest address region are Reserved for Future Use (RFU). The bits in these RFU bytes may be programmed by the host system but it must be understood that a future device may use those bits for protection of a larger OTP space. The bytes are erased when shipped from Cypress.”

However I was curious about the randomization, how can we ensure that each device is random.  Is there a possibility that a sequence can be determined.  Do you have any information regarding this?
