These APIs are not multi-thread safe or source including mutex, so at RTOS version they are dropped. You can also use them but just "using" in case that you add them to LD file.

Why RTOS SDK have less Rom Pointers than the Non-OS SDK

2018-06-13T18:42:02+08:00

I writing a bootloader for myself and wanted access to 4 rom based functions.

They appear in the NON-OS SDK file eagle.rom.addr.v6.ld:

The functions are: ets_printf, ets_putc, SPIRead, and SPIWrite.

The last two are very important since they are required for bootloader operation. The two "ets_" functions are for exporting debug data during the boot process.

I don't use the NON-OS SDK since I prefer the RTOS version.

To my surprise, those functions don't exist in the RTOS SDK.

Can someone tell me the equivalent function names in the RTOS_SDK?

Why would common low-level functions be in one SDK and not the other?

Thanks.
