[SPI-855] Flash Boot Fails at 1.8 V VDD_SPI
Description
The voltage corresponding to the default value of EXT_LDO_DREF is not 1.8 V, and the chip cannot boot from flash under 1.8 V VDD_SPI conditions.
Workaround
Boot from flash using 3.3 V VDD_SPI.
Solution
To be fixed in the next chip revision.
[ECDSA_DS-836] Signatures with Invalid r and s Values Are Incorrectly Accepted
Description
When the signature {r = 0 or n, s = 0 or n} with invalid r and s values is submitted to the ECDSA_DS peripheral against any message and public key, the peripheral incorrectly reports the signature as “valid”.
Workarounds
Use RSA_DS Secure Boot instead of ECDSA_DS Secure Boot.
Solution
No fix scheduled.
