Hi, I am working on linker files. I have a group like this:
group xyz (ordered, run_addr = mem:mpe:pspr0, copy)
{
select ".text.xyz";
} Iam trying to place the code in this PSPR section, but I am getting a linker error like: ltc E121: relocation error in "task1": relocation value 0x80225c20, type rel24 or abs24, offset 0x10, section ".text.CPU1_CODE" at address 0x7010028c is not a valid address in R_TRICORE_24REL. Hint: check the mapfile for a section that occupies this address.
ltc F019: unrecoverable error: fatal locate error. Can someone help me in resolving this?

Hi
We are evaluating S29GL064S as the replacement due to EOL of S29GL064N.
The problem is that the long programming time of S29GL064S caused the out of system specification at start up time.
The difference between S29GL064S and S29GL064N is write buffer size.
S29GL064N : 16-word / 32-byte write buffer which reduces overall programming time for multiple-word updates
S29GL064S : 128-word / 256-byte write buffer which reduces overall programming time for multiple-word updates
Are there any possibilities large write buffer size caused long programming time ?
Best regards,

Show LessAlthough it is for medical products, there are no special requirements for component warranties, and the contents will be the same as for normal electrical products,
They do not require any special quality assurance for medical applications.
Are there any restrictions for medical applications?
I think this product can be used with x1SPI and x8SPI specifications, but is it correct to say that it cannot be used with QSPI?
Also, in case of using x1SPI, I think DQ[7:2] is not available, but do I need to prepare any pull-up, pull-down, etc.?
When the power was turned on, "INVALID PARAMETER" was issued, and the parameters that should have been written at the time of shipping inspection were lost.
Repeated power on/off did not restore symptoms.
For confirmation, write down the parameters and analog adjustment values at the time of shipping inspection, and confirm that they can be written normally.
When the power was turned off and ON once at that time, "INVALID PARAMETER" was issued again, and it was confirmed that all adjustment values were off.
。 When I replaced it with a new board and turned the power off and ON again, it was confirmed that the adjustment value did not disappear and started up normally.
Writing is performed from the microcontroller via an external bus. Please tell us if you think there are any factors in the above symptoms.
Please let us know if there are any possible causes or countermeasures that cause data written by power ON / OFF to disappear as described above.

Show LessWhat is the default SecSi Sector Factory Lock value for this device.
I am looking to confirm a datecode on S29GL512P10TFIR10, i have attached an image and wondered if you could help I believe the date code format is the XXX 523 with first digit representing the year and the 2nd and third digit representing the week. I can't correlate whether the 5 indicates 2005 or 2015.
If you could shed some light on this matter it would be greatly appreciated.
Thanks
