New ContributorMAX 10 Erasing via On-Chip Flash Intel FPGA IP - SOLVED
Dear friends,
I'm using MAX10 (10M08DAF484C8GES), Quartus 18.1 and On-Chip Flash Intel FPGA IP.
My problem is:
When I need erase Sector ID1 or ID2 (or another), the "busy" from Core status Register goes to High (2'b01 BUSY_ERASE) and next clock goes to Low (2'b00 IDLE). But the "es (erase successful)" is Low (1'b0 Erase failed). What can i do?
wp (Sector ID x write protection) is disable, sp (Sector ID 1 protection bit) is Low to (I can't setup, but I read 0).
It's normaly, when "busy" goes High (BUSY_ERASE) and next clock goes Low (IDDLE)?
My simplified code:
erase_state: process(PIN_OSCILATOR)
begin
if(rising_edge(PIN_OSCILATOR)) then
if(flagErase='1') then
actionErase<='1';
end if;
case stateErase is
when ERASE_READSTATUS_A_ON =>
flashConfigAddr<='0'; --Status register
flashConfigRead<='1';
stateErase<=ERASE_READSTATUS_A_OFF;
when ERASE_READSTATUS_A_OFF =>
flashConfigRead<='0';
stateErase<=ERASE_READSTATUS_A_VALUE;
when ERASE_READSTATUS_A_VALUE =>
flashStatus<=flashConfigReadData(9 downto 0);
stateErase<=ERASE_DISABLEWP_ON;
when ERASE_DISABLEWP_ON =>
if(flashStatus(1 downto 0)="00") then --Idle
flashConfigAddr<='1'; --Control register
flashConfigWrite<='1';

stateErase<=ERASE_DISABLEWP_OFF;
else
stateErase<=ERASE_READSTATUS_A_ON; --busy, testing again
end if;

stateErase<=ERASE_STANDBY;
flashConfigWrite<='0';
flashConfigRead<='0';
flashStatus<= (others=>'0');
end if;
end case;
end if;
end process erase_state;I send IP setting and Scope signals (Read and Write signals are avmm_csr_read and avmm_csr_write, next signals are Core Status Register from flashStatus on my code).
Thank you, Tomas
