OMAPL138 boot issue at high temperature

Hello,

I am using the OMAPL138 device.

When we power up the system at high temperatures, the device does not perform boot from the SPI Flash. (Connected an emulator and saw that it did not porform BOOT).

If the device is allready working, you can go to higher temperatures with no problem. it continues to work well.

Please advice on what can be the cause of such an issue?

I've seen at the device errata about the resistors on the BOOTCFG pins and changed the values to 2K and it did not change a thing.

Thank you,

Svetlana.
