# General
|

|
|
|
||
|
|
All projects built with the nrf5x PAL need to set `DL_MAX_FRAME_SIZE=250` via
|
||
|
|
a global define, because the nrf5x doesn't support the default frame size.
|
||
|
|
|
||
|
|
To use the PAL together with other I2C devices and be able to run it also on a BLE Shield2Go
|
||
|
|
make a global define `IFX_2GO_SUPPORT`.

# Nordic SDK `nrf_crypto` backend
|
||
|
|
|
||
|
|
To use the OPTIGA with the `nrf_crypto` API the Nordic SDK needs to be modified
|
||
|
|
according to the following steps.
|
||
|
|
|
||
|
|
Locate the folder <NRF_SDK>/components/libraries/crypto/. In each file listed in
|
||
|
|
the following table locate the include statement section starting with the
|
||
|
|
comment `// Include all backends`.
|
||
|
|
|
||
|
|
Append the corresponding OPTIGA backend header file include statement at the end
|
||
|
|
of each respective include block.
|
||
|
|
|
||
|

# Memory Allocation
|
||
|
|
|
||
|
|
The library allocates memory on the heap. To ensure correct operation the heap
|
||
|
|
must be sufficiently large, e.g. 8,192 Bytes.
