S25HL02GTDPBHV053 - Safeboot Configuration Corruption Detection 0x41

tczpkami · ‎Dec 03, 2021

What is the procedure of restoring the memory to the factory state when SPI Status Register 1 = 0x41
This can be done through the SafeBoot recovery option.
I want to set the default value of SR / CR

Attached is part of the report from Infineon.
I would like to use the JTAG interface to fix this problem.

Hello,

Here is the suggested flow to recover from register corruption failure:

Pre-requisitions:

Interface Protocol = Single SPI (1S-1S-1S)
Address Bytes = 4 Byte Address Mode Only
Frequency of Operation = Maximum
Register Read Latency = 2 Clock Cycles
Output Impedance = 45Ω

SafeBoot recovery flow:

Read Status Register 1, if SR1=0x61, it is flash initialization failure, hardware reset the board to fix the issue. If SR1=0x41, continue the following steps
Clear Status Register (command 0x30)
Write Enable (command 0x06)
Write Any Register (command 0x71 + die1 register 4-byte address + desired register configuration value) (if multiple non-volatile registers need to be configured, repeat this step with respective register 4-byte address and desired registers values)
Write Any Register (command 0x71 + die2 register 4-byte address + desired register configuration value) (if multiple non-volatile registers need to be configured, repeat this step with respective register 4-byte address and desired registers values)
Change host controller interface to the same as register configurations.

Thank you

Regards,

Bushra
