AM2632: SoC ID over UART boot mode

HS FAE Germany

Part Number: AM2632

Tool/software:

Hi,
customer want to read the SoC ID over the boot UART interface and not directly after power up.
Is there any UART boot command to read the SoC ID?
Customer can't provide a POR externaly in production. Is there any command to provoke an POR/reset so boot mode will start?

Regards, Holger

Since the SOC Id is printed by ROM bootloader, and ROM bootloader is fixed it does not allow any external commands also.

They can use the PMIC to provide the POR if they cannot provide externally. Please ask customer to explore the PMIC option

Hi,
that is not exactly what they want. They now do it so that the OtpKeyWriter does a reset and the application page waits until the desired string has been transmitted via the UART.

Ok I get it, but it is not possible to read SOC ID in any other way.
