When the boot signal is effective, the reset signal is masked, and the enable signals of the OTP wrapper module and the SPI wrapper module are assigned according to the boot selection signal. The selection signal of the boot mode is 1 bit of external input and then the data in the memory is read out and written into SRAM.

It has a SoC. That SoC has a small amount of internal mask ROM for its boot loader. It boots from a managed nand Flash. In this particular case I used eMMC. This is used for basically everything - the second stage boot loader, the main software image(s), manufacturing settings, user settings, etc. It also has a small SPI FRAM device for some

Second Stage Boot Loader (SSBL), which further initializes additional peripherals as needed. This is U-Boot proper combined with an OpenSBI fw_dynamic firmware image. msel=6 means FSBL and SSBL are both on the QSPI flash. msel=11 means FSBL and SSBL are both on the SD card.

Oct 09, 2012 · Using a USBtinyISP, I can successfully burn-in the default bootloader through the Arduino IDE. I can then upload the OpenLog_v3 sketch okay and the logger works fine. But if I try to upload the sketch a second time (with or without any changes to the code), I get a "stk500_getsync(): not in sync: resp=0x00" from avrdude.

I have all applications running in ITC so they use the QSPI flash for parameter and file systems without any problems with sharing with code. In fact I avoid SDRAM since it doesn't allow code to be protected and I never had a program so large that external memory was needed.
