Hello,

does anyone know how flashing with the ST10 Flasher works concerning the memory configuration (referring to section 16.2.5 of the ST10 User Manual on page 284)?

Should it still work if I set the EA pin to 0 (for writing to external RAM instead of internal flash)?

If no (which is my case): Why not and how can I implement a bootloader which writes to RAM-location 0x0 in BSL-Mode (referring to figure 129 on page 285)?

Thanks.

Yes, this is what I would like to do with my own bootstraploader.

Figure 129 on page 285 of the ST10F276 user manual is a little bit confusing.

Does this memory configuration also apply for writing to external RAM location 0x0 in BSL-mode?

(My configuration after reset:

EA-pin: low;

port0: 0xE2A0)
